Greatest Common Factor
We found the factors 28,56,136 . The biggest common factor number is the GCF number.
So the greatest common factor 28,56,136 is 4.
Lets's calculate LCM of 58,28,537
2 | 58, 28, 537 |
29, 14, 537 |
∴ So the LCM of the given numbers is 2 x 29 x 14 x 537 = 436044
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/436044
Therefore, the GCF of Fractions 28/58,56/28,136/537 is 4/436044
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 58,28,537 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(58,28,537) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(58,28,537) x common factors =1 x 2 = 2
LCM(58,28,537) = ( 58 × 28 × 537 ) / 2
LCM(58,28,537) = 872088 / 2
LCM(58,28,537) = 436044
