So the greatest common factor 615,798 is 3.
Lets's calculate LCM of 744,492
2 | 744, 492 |
2 | 372, 246 |
3 | 186, 123 |
62, 41 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 62 x 41 = 30504
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/30504
Therefore, the GCF of Fractions 615/744,798/492 is 3/30504
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 744,492 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(744,492) = 12
common factors(in case of two or more numbers have common factors) = 1
GCF(744,492) x common factors =12 x 1 = 12
LCM(744,492) = ( 744 × 492 ) / 12
LCM(744,492) = 366048 / 12
LCM(744,492) = 30504
