Lets's calculate LCM of 856,6144
2 | 856, 6144 |
2 | 428, 3072 |
2 | 214, 1536 |
107, 768 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 107 x 768 = 657408
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/657408
Therefore, the GCF of Fractions 357/856,8400/6144 is 21/657408
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 856,6144 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(856,6144) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(856,6144) x common factors =8 x 1 = 8
LCM(856,6144) = ( 856 × 6144 ) / 8
LCM(856,6144) = 5259264 / 8
LCM(856,6144) = 657408
