∴ So the GCF of the given numbers is 2 x 2 x 3 = 12
Now, list down the factors of 744
:1,2,3,4,6,8,12,24,31,62,93,124,186,248,372,744
Now, list down the factors of 420
:1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Greatest Common Factor
We found the factors 744,420 . The biggest common factor number is the GCF number.
So the greatest common factor 744,420 is 12.
Lets's calculate LCM of 88,909
Given numbers has no common factors except 1. So, there LCM is their product i.e 79992
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/79992
Therefore, the GCF of Fractions 744/88,420/909 is 12/79992
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 88,909 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(88,909) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(88,909) x common factors =1 x 1 = 1
LCM(88,909) = ( 88 × 909 ) / 1
LCM(88,909) = 79992 / 1
LCM(88,909) = 79992
