1,491
Greatest Common Factor
We found the factors 639,900,491 . The biggest common factor number is the GCF number.
So the greatest common factor 639,900,491 is 1.
Lets's calculate LCM of 22,55,917
11 | 22, 55, 917 |
2, 5, 917 |
∴ So the LCM of the given numbers is 11 x 2 x 5 x 917 = 100870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/100870
Therefore, the GCF of Fractions 639/22,900/55,491/917 is 1/100870
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 22,55,917 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,55,917) = 1
common factors(in case of two or more numbers have common factors) = 11
GCF(22,55,917) x common factors =1 x 11 = 11
LCM(22,55,917) = ( 22 × 55 × 917 ) / 11
LCM(22,55,917) = 1109570 / 11
LCM(22,55,917) = 100870
