Lets's calculate LCM of 742,686,398
2 | 742, 686, 398 |
7 | 371, 343, 199 |
53, 49, 199 |
∴ So the LCM of the given numbers is 2 x 7 x 53 x 49 x 199 = 7235242
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7235242
Therefore, the GCF of Fractions 650/742,935/686,397/398 is 1/7235242
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 742,686,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(742,686,398) = 2
common factors(in case of two or more numbers have common factors) = 14
GCF(742,686,398) x common factors =2 x 14 = 28
LCM(742,686,398) = ( 742 × 686 × 398 ) / 28
LCM(742,686,398) = 202586776 / 28
LCM(742,686,398) = 7235242
