We found the factors 63,209,170 . The biggest common factor number is the GCF number.
So the greatest common factor 63,209,170 is 1.
Lets's calculate LCM of 426,740,689
2 | 426, 740, 689 |
213, 370, 689 |
∴ So the LCM of the given numbers is 2 x 213 x 370 x 689 = 108600180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/108600180
Therefore, the GCF of Fractions 63/426,209/740,170/689 is 1/108600180
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 426,740,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(426,740,689) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(426,740,689) x common factors =1 x 2 = 2
LCM(426,740,689) = ( 426 × 740 × 689 ) / 2
LCM(426,740,689) = 217200360 / 2
LCM(426,740,689) = 108600180
