Lets's calculate LCM of 370,2598
2 | 370, 2598 |
185, 1299 |
∴ So the LCM of the given numbers is 2 x 185 x 1299 = 480630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 84/480630
Therefore, the GCF of Fractions 252/370,7980/2598 is 84/480630
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 370,2598 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(370,2598) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(370,2598) x common factors =2 x 1 = 2
LCM(370,2598) = ( 370 × 2598 ) / 2
LCM(370,2598) = 961260 / 2
LCM(370,2598) = 480630
