1,19,419,7961
Greatest Common Factor
We found the factors 617,7961 . The biggest common factor number is the GCF number.
So the greatest common factor 617,7961 is 1.
Lets's calculate LCM of 672,639
3 | 672, 639 |
224, 213 |
∴ So the LCM of the given numbers is 3 x 224 x 213 = 143136
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/143136
Therefore, the GCF of Fractions 617/672,7961/639 is 1/143136
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 672,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(672,639) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(672,639) x common factors =3 x 1 = 3
LCM(672,639) = ( 672 × 639 ) / 3
LCM(672,639) = 429408 / 3
LCM(672,639) = 143136
