Lets's calculate LCM of 936,728
2 | 936, 728 |
2 | 468, 364 |
2 | 234, 182 |
13 | 117, 91 |
9, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 13 x 9 x 7 = 6552
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6552
Therefore, the GCF of Fractions 677/936,643/728 is 1/6552
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 936,728 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(936,728) = 104
common factors(in case of two or more numbers have common factors) = 1
GCF(936,728) x common factors =104 x 1 = 104
LCM(936,728) = ( 936 × 728 ) / 104
LCM(936,728) = 681408 / 104
LCM(936,728) = 6552
