So the greatest common factor 35,91,741 is 1.
Lets's calculate LCM of 688,420,272
2 | 688, 420, 272 |
2 | 344, 210, 136 |
2 | 172, 105, 68 |
2 | 86, 105, 34 |
43, 105, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 43 x 105 x 17 = 1228080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1228080
Therefore, the GCF of Fractions 35/688,91/420,741/272 is 1/1228080
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 688,420,272 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(688,420,272) = 4
common factors(in case of two or more numbers have common factors) = 16
GCF(688,420,272) x common factors =4 x 16 = 64
LCM(688,420,272) = ( 688 × 420 × 272 ) / 64
LCM(688,420,272) = 78597120 / 64
LCM(688,420,272) = 1228080
