So the greatest common factor 639,527 is 1.
Lets's calculate LCM of 642,862
2 | 642, 862 |
321, 431 |
∴ So the LCM of the given numbers is 2 x 321 x 431 = 276702
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/276702
Therefore, the GCF of Fractions 639/642,527/862 is 1/276702
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 642,862 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,862) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(642,862) x common factors =2 x 1 = 2
LCM(642,862) = ( 642 × 862 ) / 2
LCM(642,862) = 553404 / 2
LCM(642,862) = 276702
