Lets's calculate GCF of 961,155
31 | 961, 155 |
31, 5 |
∴ So the GCF of the given numbers is 31 = 31
Now, list down the factors of 961
:1,31,961
Now, list down the factors of 155
:1,5,31,155
Greatest Common Factor
We found the factors 961,155 . The biggest common factor number is the GCF number.
So the greatest common factor 961,155 is 31.
Lets's calculate LCM of 584,790
2 | 584, 790 |
292, 395 |
∴ So the LCM of the given numbers is 2 x 292 x 395 = 230680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 31/230680
Therefore, the GCF of Fractions 961/584,155/790 is 31/230680
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 584,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(584,790) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(584,790) x common factors =2 x 1 = 2
LCM(584,790) = ( 584 × 790 ) / 2
LCM(584,790) = 461360 / 2
LCM(584,790) = 230680
