The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

To find the HCF (a.k.a GCD or GCF) or LCM of decimals, you need to convert the decimal numbers to a fraction in its lowest equivalent term. For example, 0.54 gives 54/100 when written as a fraction, and it gives 27/50 when reduced to its lowest equivalent term.

LCM and prime factorisation are two opposite processes in maths. LCM pertains to two or more numbers. Factorisation pertains to only one number. ... HCF is the bunch of factors that are common to both of the above two numbers.

Divide lcm by hcf then factor that and any factorization you get can be put into two numbers that when each multiplied by hcf give you a number in a pair. If b is the other no., then, b=c/a. The sum of HCF and LCM of two numbers is 435.

So LCM is greater than HCF. LCM means Lowest Common Multiple. HCF means Highest Common Factor. Since multiple are always greater than or equal to the number and factors are always less than or equal to, we can say that multiple will always be bigger than factors and So the LCM is greater than the HCF......

The LCM of two integers is the smallest whole number that appears in both of their times tables, that is, the smallest integer that is a multiple of both numbers. For example, the LCM of 4 and 5 is 20. ... The HCF of two integers is the largest whole number that divides both numbers without leaving a remainder.

Step 2: Factor out (or divide out) the greatest common factor from each term. Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common. Step 2: Factor out (or divide out) the greatest common factor from each term.

The Least Common Multiple ( LCM ) is also referred to as the Lowest Common Multiple ( LCM ) and Least Common Divisor ( LCD) . For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM(2,3) = 6 and LCM(6,10) = 30.

It is very easy if we know the meaning of LCM and HCF. ... So, whenever you are required to find a number that is divisible by more than one number, you have to find LCM. Highest Common Factor, also called HCF, is that highest number that completely divides a given set of number.
