What is the grreatest common factor of 16 24 and 30?
93202
greatest common factor of 16,24 and 30\nfirst of all we have to factorize it\n16= 2*2*2*2\n24= 2*2*2*3\n30= 2*3*5\n\nso greatest common factor in this case is the greatest number, that 16,24 and 30 are divisible by it.\n\nso the only common number in all the three is "2" and it is also the greatest common factor because the numbers above don't have any other common factor\nGCF=2\n\nNow let us find the GCF (greatest common factor) of other numbers.\neg:  12,24,48\n\nfactorize it first\n12= 2*2*3\n24= 2*2*2*3\n48= 2*2*2*2*3\n\nthe common factors in all the three are two times two and one time three (look carefully)\nGCF= 2*2*3\nGCF= 12\nthat is the greatest common factor.\n\n1st answer gcf =2  and 2nd answer gcf=12

Easy. 40 divided by 2 is 20. Take half of 40.  OR 40x0.5

Mr Wonderful is right.  the quick common denominator is 65*26= 1690, but the numbers have a common factor of 13.  divide 1690/13=130.\n\na simpler example: given 8 and 12, QCD = 96, but GCF = 4, so LCD = 96/4 = 24.

20 - - 4 = 24\nminus and minus = plus\nie\n20 - - 4 = 20 + 4 = 24

The greatest common factor of two non-zero integers is the largest positive integer that divides both numbers without remainder. To find the GCF of 2 numbers, make a list of their factors (the numbers that they are divisible by)For example:\n\nFactors of 25: 1, 5, 25 \nFactos of 36: 1, 2, 3, 4, 9, 12, 18, 36. \n\nHere you see that 25 and 36 do not have a common factor (other than 1)...maybe you typed the question wrong?\nGood luck anyway...;-)

Convert the fractions to a common denominator which is 24\n2/3 = 16/24\n3/8 = 9/24\n5/12 = 10/24\n\nThen add them up. \n16 + 9 + 10 = 35 or 35/24 \n\n35/24 = 1-11/24

GCF=greatest common factor is the no that is the gteatest factor of two or more no is the GCF \n\nEX) 12=1,2,3,4,6,12\n    30=1,2,3,5,6,10,15,30\n\nAs you can see 6 is the greatest in here that is common with 12 and 30

There are two common ways.   If the numbers are small and you can eyeball it, the best way is to split each number into it's prime factors and then cancel out.\n\nE.g. 12 and 30\n\n12 = 2 x 2 x 3\n30 = 2 x 3 x 5\n\nGreatest common divisor = 2 x 3 = 6\n\nThe least common multiple is related to the GCD by\n\nA x B = GCD x LCM\n\nThe better way to do GCD's for big numbers is to note that if a number divides A and B, then it divides A - B, A + B, and in fact A - k*B for any k (i.e. A minus any multiple of B).\n\nSo you take the bigger number, say A, do long division with remainder to get:\n\nA = k * B + remainder\n\nGCD(A, B) = GCD( B, remainder)\n\nBoth B and the remainder are smaller than A.  You keep doing that until the number divides exactly or you end up with one.  If the number divides exactly that is the GCD, otherwise it's one.\n\nE.g. \n30 = 12 * 2 + 6\n12 = 6 * 2 exactly GCD = 6
