1,7,13,91
Factors of 209
List of positive integer factors of 209 that divides 209 without a remainder.
1,11,19,209
Greatest Common Factor
We found the factors 52,10,91,209 . The biggest common factor number is the GCF number.
So the greatest common factor 52,10,91,209 is 1.
Lets's calculate LCM of 78,67,18,80
2 | 78, 67, 18, 80 |
3 | 39, 67, 9, 40 |
13, 67, 3, 40 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 67 x 3 x 40 = 627120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/627120
Therefore, the GCF of Fractions 52/78,10/67,91/18,209/80 is 1/627120
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 78,67,18,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,67,18,80) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(78,67,18,80) x common factors =1 x 12 = 12
LCM(78,67,18,80) = ( 78 × 67 × 18 × 80 ) / 12
LCM(78,67,18,80) = 7525440 / 12
LCM(78,67,18,80) = 627120
