Greatest Common Factor
We found the factors 85,11,10,31 . The biggest common factor number is the GCF number.
So the greatest common factor 85,11,10,31 is 1.
Lets's calculate LCM of 52,19,78,722
2 | 52, 19, 78, 722 |
13 | 26, 19, 39, 361 |
19 | 2, 19, 3, 361 |
2, 1, 3, 19 |
∴ So the LCM of the given numbers is 2 x 13 x 19 x 2 x 1 x 3 x 19 = 56316
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/56316
Therefore, the GCF of Fractions 85/52,11/19,10/78,31/722 is 1/56316
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 52,19,78,722 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(52,19,78,722) = 1
common factors(in case of two or more numbers have common factors) = 988
GCF(52,19,78,722) x common factors =1 x 988 = 988
LCM(52,19,78,722) = ( 52 × 19 × 78 × 722 ) / 988
LCM(52,19,78,722) = 55640208 / 988
LCM(52,19,78,722) = 56316
