Greatest Common Factor
We found the factors 38,79,29,988 . The biggest common factor number is the GCF number.
So the greatest common factor 38,79,29,988 is 1.
Lets's calculate LCM of 39,60,52,53
2 | 39, 60, 52, 53 |
2 | 39, 30, 26, 53 |
3 | 39, 15, 13, 53 |
13 | 13, 5, 13, 53 |
1, 5, 1, 53 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 13 x 1 x 5 x 1 x 53 = 41340
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/41340
Therefore, the GCF of Fractions 38/39,79/60,29/52,988/53 is 1/41340
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 39,60,52,53 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,60,52,53) = 1
common factors(in case of two or more numbers have common factors) = 156
GCF(39,60,52,53) x common factors =1 x 156 = 156
LCM(39,60,52,53) = ( 39 × 60 × 52 × 53 ) / 156
LCM(39,60,52,53) = 6449040 / 156
LCM(39,60,52,53) = 41340
