Greatest Common Factor
We found the factors 61,78,887 . The biggest common factor number is the GCF number.
So the greatest common factor 61,78,887 is 1.
Lets's calculate LCM of 170,612,372
2 | 170, 612, 372 |
2 | 85, 306, 186 |
3 | 85, 153, 93 |
17 | 85, 51, 31 |
5, 3, 31 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 17 x 5 x 3 x 31 = 94860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/94860
Therefore, the GCF of Fractions 61/170,78/612,887/372 is 1/94860
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 170,612,372 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(170,612,372) = 2
common factors(in case of two or more numbers have common factors) = 204
GCF(170,612,372) x common factors =2 x 204 = 408
LCM(170,612,372) = ( 170 × 612 × 372 ) / 408
LCM(170,612,372) = 38702880 / 408
LCM(170,612,372) = 94860
