:1,251
Greatest Common Factor
We found the factors 947,251 . The biggest common factor number is the GCF number.
So the greatest common factor 947,251 is 1.
Lets's calculate LCM of 685,642
Given numbers has no common factors except 1. So, there LCM is their product i.e 439770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/439770
Therefore, the GCF of Fractions 947/685,251/642 is 1/439770
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 685,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(685,642) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(685,642) x common factors =1 x 1 = 1
LCM(685,642) = ( 685 × 642 ) / 1
LCM(685,642) = 439770 / 1
LCM(685,642) = 439770
