Greatest Common Factor
We found the factors 637,958 . The biggest common factor number is the GCF number.
So the greatest common factor 637,958 is 1.
Lets's calculate LCM of 420,681
3 | 420, 681 |
140, 227 |
∴ So the LCM of the given numbers is 3 x 140 x 227 = 95340
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/95340
Therefore, the GCF of Fractions 637/420,958/681 is 1/95340
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 420,681 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,681) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(420,681) x common factors =3 x 1 = 3
LCM(420,681) = ( 420 × 681 ) / 3
LCM(420,681) = 286020 / 3
LCM(420,681) = 95340
