So the greatest common factor 715,210 is 5.
Lets's calculate LCM of 216,956
2 | 216, 956 |
2 | 108, 478 |
54, 239 |
∴ So the LCM of the given numbers is 2 x 2 x 54 x 239 = 51624
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/51624
Therefore, the GCF of Fractions 715/216,210/956 is 5/51624
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 216,956 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(216,956) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(216,956) x common factors =4 x 1 = 4
LCM(216,956) = ( 216 × 956 ) / 4
LCM(216,956) = 206496 / 4
LCM(216,956) = 51624
