Greatest Common Factor
We found the factors 64,901,319 . The biggest common factor number is the GCF number.
So the greatest common factor 64,901,319 is 1.
Lets's calculate LCM of 61,12,405
3 | 61, 12, 405 |
61, 4, 135 |
∴ So the LCM of the given numbers is 3 x 61 x 4 x 135 = 98820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/98820
Therefore, the GCF of Fractions 64/61,901/12,319/405 is 1/98820
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 61,12,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,12,405) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(61,12,405) x common factors =1 x 3 = 3
LCM(61,12,405) = ( 61 × 12 × 405 ) / 3
LCM(61,12,405) = 296460 / 3
LCM(61,12,405) = 98820
