Greatest Common Factor
We found the factors 24,70,74,60 . The biggest common factor number is the GCF number.
So the greatest common factor 24,70,74,60 is 2.
Lets's calculate LCM of 21,67,83,13
Given numbers has no common factors except 1. So, there LCM is their product i.e 1518153
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1518153
Therefore, the GCF of Fractions 24/21,70/67,74/83,60/13 is 2/1518153
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 21,67,83,13 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,67,83,13) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,67,83,13) x common factors =1 x 1 = 1
LCM(21,67,83,13) = ( 21 × 67 × 83 × 13 ) / 1
LCM(21,67,83,13) = 1518153 / 1
LCM(21,67,83,13) = 1518153
