5 | 505, 690 |
101, 138 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 505
:1,5,101,505
Now, list down the factors of 690
:1,2,3,5,6,10,15,23,30,46,69,115,138,230,345,690
Greatest Common Factor
We found the factors 505,690 . The biggest common factor number is the GCF number.
So the greatest common factor 505,690 is 5.
Lets's calculate LCM of 766,280
2 | 766, 280 |
383, 140 |
∴ So the LCM of the given numbers is 2 x 383 x 140 = 107240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/107240
Therefore, the GCF of Fractions 505/766,690/280 is 5/107240
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 766,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(766,280) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(766,280) x common factors =2 x 1 = 2
LCM(766,280) = ( 766 × 280 ) / 2
LCM(766,280) = 214480 / 2
LCM(766,280) = 107240
