Greatest Common Factor
We found the factors 62,12,92,78 . The biggest common factor number is the GCF number.
So the greatest common factor 62,12,92,78 is 2.
Lets's calculate LCM of 69,29,67,77
Given numbers has no common factors except 1. So, there LCM is their product i.e 10323159
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/10323159
Therefore, the GCF of Fractions 62/69,12/29,92/67,78/77 is 2/10323159
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 69,29,67,77 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,29,67,77) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(69,29,67,77) x common factors =1 x 1 = 1
LCM(69,29,67,77) = ( 69 × 29 × 67 × 77 ) / 1
LCM(69,29,67,77) = 10323159 / 1
LCM(69,29,67,77) = 10323159
