Greatest Common Factor
We found the factors 40,86,45,567 . The biggest common factor number is the GCF number.
So the greatest common factor 40,86,45,567 is 1.
Lets's calculate LCM of 36,36,94,18
2 | 36, 36, 94, 18 |
2 | 18, 18, 47, 9 |
3 | 9, 9, 47, 9 |
3 | 3, 3, 47, 3 |
1, 1, 47, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 1 x 47 x 1 = 1692
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1692
Therefore, the GCF of Fractions 40/36,86/36,45/94,567/18 is 1/1692
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 36,36,94,18 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,36,94,18) = 2
common factors(in case of two or more numbers have common factors) = 648
GCF(36,36,94,18) x common factors =2 x 648 = 1296
LCM(36,36,94,18) = ( 36 × 36 × 94 × 18 ) / 1296
LCM(36,36,94,18) = 2192832 / 1296
LCM(36,36,94,18) = 1692
