Greatest Common Factor
We found the factors 72,53,621 . The biggest common factor number is the GCF number.
So the greatest common factor 72,53,621 is 1.
Lets's calculate LCM of 702,123,506
2 | 702, 123, 506 |
3 | 351, 123, 253 |
117, 41, 253 |
∴ So the LCM of the given numbers is 2 x 3 x 117 x 41 x 253 = 7281846
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7281846
Therefore, the GCF of Fractions 72/702,53/123,621/506 is 1/7281846
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 702,123,506 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(702,123,506) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(702,123,506) x common factors =1 x 6 = 6
LCM(702,123,506) = ( 702 × 123 × 506 ) / 6
LCM(702,123,506) = 43691076 / 6
LCM(702,123,506) = 7281846
