Greatest Common Factor
We found the factors 637,421 . The biggest common factor number is the GCF number.
So the greatest common factor 637,421 is 1.
Lets's calculate LCM of 624,916
2 | 624, 916 |
2 | 312, 458 |
156, 229 |
∴ So the LCM of the given numbers is 2 x 2 x 156 x 229 = 142896
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/142896
Therefore, the GCF of Fractions 637/624,421/916 is 1/142896
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 624,916 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(624,916) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(624,916) x common factors =4 x 1 = 4
LCM(624,916) = ( 624 × 916 ) / 4
LCM(624,916) = 571584 / 4
LCM(624,916) = 142896
