:1,2,71,142
Greatest Common Factor
We found the factors 133,142 . The biggest common factor number is the GCF number.
So the greatest common factor 133,142 is 1.
Lets's calculate LCM of 556,280
2 | 556, 280 |
2 | 278, 140 |
139, 70 |
∴ So the LCM of the given numbers is 2 x 2 x 139 x 70 = 38920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38920
Therefore, the GCF of Fractions 133/556,142/280 is 1/38920
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 556,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(556,280) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(556,280) x common factors =4 x 1 = 4
LCM(556,280) = ( 556 × 280 ) / 4
LCM(556,280) = 155680 / 4
LCM(556,280) = 38920
