Lets's calculate LCM of 915,420
3 | 915, 420 |
5 | 305, 140 |
61, 28 |
∴ So the LCM of the given numbers is 3 x 5 x 61 x 28 = 25620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25620
Therefore, the GCF of Fractions 4971/915,4655/420 is 1/25620
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 915,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(915,420) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(915,420) x common factors =15 x 1 = 15
LCM(915,420) = ( 915 × 420 ) / 15
LCM(915,420) = 384300 / 15
LCM(915,420) = 25620
