Greatest Common Factor
We found the factors 90,711,698 . The biggest common factor number is the GCF number.
So the greatest common factor 90,711,698 is 1.
Lets's calculate LCM of 51,26,681
3 | 51, 26, 681 |
17, 26, 227 |
∴ So the LCM of the given numbers is 3 x 17 x 26 x 227 = 301002
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/301002
Therefore, the GCF of Fractions 90/51,711/26,698/681 is 1/301002
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 51,26,681 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,26,681) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(51,26,681) x common factors =1 x 3 = 3
LCM(51,26,681) = ( 51 × 26 × 681 ) / 3
LCM(51,26,681) = 903006 / 3
LCM(51,26,681) = 301002
