So the greatest common factor 34,661,810 is 1.
Lets's calculate LCM of 756,640,785
2 | 756, 640, 785 |
2 | 378, 320, 785 |
5 | 189, 160, 785 |
189, 32, 157 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 189 x 32 x 157 = 18990720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18990720
Therefore, the GCF of Fractions 34/756,661/640,810/785 is 1/18990720
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 756,640,785 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(756,640,785) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(756,640,785) x common factors =1 x 20 = 20
LCM(756,640,785) = ( 756 × 640 × 785 ) / 20
LCM(756,640,785) = 379814400 / 20
LCM(756,640,785) = 18990720
