So the greatest common factor 947,420 is 1.
Lets's calculate LCM of 598,280
2 | 598, 280 |
299, 140 |
∴ So the LCM of the given numbers is 2 x 299 x 140 = 83720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/83720
Therefore, the GCF of Fractions 947/598,420/280 is 1/83720
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 598,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(598,280) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(598,280) x common factors =2 x 1 = 2
LCM(598,280) = ( 598 × 280 ) / 2
LCM(598,280) = 167440 / 2
LCM(598,280) = 83720
