List of positive integer factors of 79 that divides 79 without a remainder.
1,79
Greatest Common Factor
We found the factors 72,91,67,79 . The biggest common factor number is the GCF number.
So the greatest common factor 72,91,67,79 is 1.
Lets's calculate LCM of 36,45,15,549
3 | 36, 45, 15, 549 |
3 | 12, 15, 5, 183 |
5 | 4, 5, 5, 61 |
4, 1, 1, 61 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 4 x 1 x 1 x 61 = 10980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10980
Therefore, the GCF of Fractions 72/36,91/45,67/15,79/549 is 1/10980
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 36,45,15,549 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,45,15,549) = 3
common factors(in case of two or more numbers have common factors) = 405
GCF(36,45,15,549) x common factors =3 x 405 = 1215
LCM(36,45,15,549) = ( 36 × 45 × 15 × 549 ) / 1215
LCM(36,45,15,549) = 13340700 / 1215
LCM(36,45,15,549) = 10980
