Lets's calculate LCM of 837,378,665
3 | 837, 378, 665 |
3 | 279, 126, 665 |
3 | 93, 42, 665 |
7 | 31, 14, 665 |
31, 2, 95 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 7 x 31 x 2 x 95 = 1113210
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1113210
Therefore, the GCF of Fractions 84/837,31/378,206/665 is 1/1113210
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 837,378,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(837,378,665) = 1
common factors(in case of two or more numbers have common factors) = 189
GCF(837,378,665) x common factors =1 x 189 = 189
LCM(837,378,665) = ( 837 × 378 × 665 ) / 189
LCM(837,378,665) = 210396690 / 189
LCM(837,378,665) = 1113210
