Greatest Common Factor
We found the factors 392,2142 . The biggest common factor number is the GCF number.
So the greatest common factor 392,2142 is 14.
Lets's calculate LCM of 42,751
Given numbers has no common factors except 1. So, there LCM is their product i.e 31542
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/31542
Therefore, the GCF of Fractions 392/42,2142/751 is 14/31542
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 42,751 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,751) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(42,751) x common factors =1 x 1 = 1
LCM(42,751) = ( 42 × 751 ) / 1
LCM(42,751) = 31542 / 1
LCM(42,751) = 31542
