So the greatest common factor 646,692,656 is 2.
Lets's calculate LCM of 63,70,740
2 | 63, 70, 740 |
5 | 63, 35, 370 |
7 | 63, 7, 74 |
9, 1, 74 |
∴ So the LCM of the given numbers is 2 x 5 x 7 x 9 x 1 x 74 = 46620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/46620
Therefore, the GCF of Fractions 646/63,692/70,656/740 is 2/46620
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 63,70,740 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,70,740) = 1
common factors(in case of two or more numbers have common factors) = 70
GCF(63,70,740) x common factors =1 x 70 = 70
LCM(63,70,740) = ( 63 × 70 × 740 ) / 70
LCM(63,70,740) = 3263400 / 70
LCM(63,70,740) = 46620
