So the greatest common factor 70,790,985 is 5.
Lets's calculate LCM of 515,666,851
37 | 515, 666, 851 |
515, 18, 23 |
∴ So the LCM of the given numbers is 37 x 515 x 18 x 23 = 7888770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/7888770
Therefore, the GCF of Fractions 70/515,790/666,985/851 is 5/7888770
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 515,666,851 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(515,666,851) = 1
common factors(in case of two or more numbers have common factors) = 37
GCF(515,666,851) x common factors =1 x 37 = 37
LCM(515,666,851) = ( 515 × 666 × 851 ) / 37
LCM(515,666,851) = 291884490 / 37
LCM(515,666,851) = 7888770
