Greatest Common Factor
We found the factors 83,82,39,189 . The biggest common factor number is the GCF number.
So the greatest common factor 83,82,39,189 is 1.
Lets's calculate LCM of 93,72,15,47
3 | 93, 72, 15, 47 |
31, 24, 5, 47 |
∴ So the LCM of the given numbers is 3 x 31 x 24 x 5 x 47 = 524520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/524520
Therefore, the GCF of Fractions 83/93,82/72,39/15,189/47 is 1/524520
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 93,72,15,47 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(93,72,15,47) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(93,72,15,47) x common factors =1 x 9 = 9
LCM(93,72,15,47) = ( 93 × 72 × 15 × 47 ) / 9
LCM(93,72,15,47) = 4720680 / 9
LCM(93,72,15,47) = 524520
