So the greatest common factor 732,9090 is 6.
Lets's calculate LCM of 624,3920
2 | 624, 3920 |
2 | 312, 1960 |
2 | 156, 980 |
2 | 78, 490 |
39, 245 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 39 x 245 = 152880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/152880
Therefore, the GCF of Fractions 732/624,9090/3920 is 6/152880
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 624,3920 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(624,3920) = 16
common factors(in case of two or more numbers have common factors) = 1
GCF(624,3920) x common factors =16 x 1 = 16
LCM(624,3920) = ( 624 × 3920 ) / 16
LCM(624,3920) = 2446080 / 16
LCM(624,3920) = 152880
