Greatest Common Factor
We found the factors 98,259,693 . The biggest common factor number is the GCF number.
So the greatest common factor 98,259,693 is 7.
Lets's calculate LCM of 23,53,430
Given numbers has no common factors except 1. So, there LCM is their product i.e 524170
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/524170
Therefore, the GCF of Fractions 98/23,259/53,693/430 is 7/524170
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 23,53,430 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,53,430) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,53,430) x common factors =1 x 1 = 1
LCM(23,53,430) = ( 23 × 53 × 430 ) / 1
LCM(23,53,430) = 524170 / 1
LCM(23,53,430) = 524170
