So the greatest common factor 81,598,789 is 1.
Lets's calculate LCM of 66,58,374
2 | 66, 58, 374 |
11 | 33, 29, 187 |
3, 29, 17 |
∴ So the LCM of the given numbers is 2 x 11 x 3 x 29 x 17 = 32538
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/32538
Therefore, the GCF of Fractions 81/66,598/58,789/374 is 1/32538
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 66,58,374 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(66,58,374) = 2
common factors(in case of two or more numbers have common factors) = 22
GCF(66,58,374) x common factors =2 x 22 = 44
LCM(66,58,374) = ( 66 × 58 × 374 ) / 44
LCM(66,58,374) = 1431672 / 44
LCM(66,58,374) = 32538
