Lets's calculate LCM of 828,639
3 | 828, 639 |
3 | 276, 213 |
92, 71 |
∴ So the LCM of the given numbers is 3 x 3 x 92 x 71 = 58788
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/58788
Therefore, the GCF of Fractions 677/828,280/639 is 1/58788
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 828,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(828,639) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(828,639) x common factors =9 x 1 = 9
LCM(828,639) = ( 828 × 639 ) / 9
LCM(828,639) = 529092 / 9
LCM(828,639) = 58788
