Greatest Common Factor
We found the factors 1978,7639 . The biggest common factor number is the GCF number.
So the greatest common factor 1978,7639 is 1.
Lets's calculate LCM of 957,9920
Given numbers has no common factors except 1. So, there LCM is their product i.e 9493440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9493440
Therefore, the GCF of Fractions 1978/957,7639/9920 is 1/9493440
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 957,9920 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(957,9920) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(957,9920) x common factors =1 x 1 = 1
LCM(957,9920) = ( 957 × 9920 ) / 1
LCM(957,9920) = 9493440 / 1
LCM(957,9920) = 9493440
