Greatest Common Factor
We found the factors 93,479,645 . The biggest common factor number is the GCF number.
So the greatest common factor 93,479,645 is 1.
Lets's calculate LCM of 42,17,491
Given numbers has no common factors except 1. So, there LCM is their product i.e 350574
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/350574
Therefore, the GCF of Fractions 93/42,479/17,645/491 is 1/350574
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 42,17,491 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,17,491) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(42,17,491) x common factors =1 x 1 = 1
LCM(42,17,491) = ( 42 × 17 × 491 ) / 1
LCM(42,17,491) = 350574 / 1
LCM(42,17,491) = 350574
