So the greatest common factor 1356,5628 is 12.
Lets's calculate LCM of 784,280
2 | 784, 280 |
2 | 392, 140 |
2 | 196, 70 |
7 | 98, 35 |
14, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 14 x 5 = 3920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/3920
Therefore, the GCF of Fractions 1356/784,5628/280 is 12/3920
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 784,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(784,280) = 56
common factors(in case of two or more numbers have common factors) = 1
GCF(784,280) x common factors =56 x 1 = 56
LCM(784,280) = ( 784 × 280 ) / 56
LCM(784,280) = 219520 / 56
LCM(784,280) = 3920
