Greatest Common Factor
We found the factors 56,63,140 . The biggest common factor number is the GCF number.
So the greatest common factor 56,63,140 is 7.
Lets's calculate LCM of 349,931,406
7 | 349, 931, 406 |
349, 133, 58 |
∴ So the LCM of the given numbers is 7 x 349 x 133 x 58 = 18845302
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/18845302
Therefore, the GCF of Fractions 56/349,63/931,140/406 is 7/18845302
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 349,931,406 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(349,931,406) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(349,931,406) x common factors =1 x 7 = 7
LCM(349,931,406) = ( 349 × 931 × 406 ) / 7
LCM(349,931,406) = 131917114 / 7
LCM(349,931,406) = 18845302
