:1,3,43,129
Greatest Common Factor
We found the factors 172,129 . The biggest common factor number is the GCF number.
So the greatest common factor 172,129 is 43.
Lets's calculate LCM of 40,584
2 | 40, 584 |
2 | 20, 292 |
2 | 10, 146 |
5, 73 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 73 = 2920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 43/2920
Therefore, the GCF of Fractions 172/40,129/584 is 43/2920
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 40,584 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,584) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(40,584) x common factors =8 x 1 = 8
LCM(40,584) = ( 40 × 584 ) / 8
LCM(40,584) = 23360 / 8
LCM(40,584) = 2920
