So the greatest common factor 73,355,280 is 1.
Lets's calculate LCM of 49,92,420
2 | 49, 92, 420 |
2 | 49, 46, 210 |
7 | 49, 23, 105 |
7, 23, 15 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 7 x 23 x 15 = 67620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/67620
Therefore, the GCF of Fractions 73/49,355/92,280/420 is 1/67620
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 49,92,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,92,420) = 1
common factors(in case of two or more numbers have common factors) = 28
GCF(49,92,420) x common factors =1 x 28 = 28
LCM(49,92,420) = ( 49 × 92 × 420 ) / 28
LCM(49,92,420) = 1893360 / 28
LCM(49,92,420) = 67620
