Greatest Common Factor
We found the factors 72,82,83,87 . The biggest common factor number is the GCF number.
So the greatest common factor 72,82,83,87 is 1.
Lets's calculate LCM of 52,60,13,255
2 | 52, 60, 13, 255 |
2 | 26, 30, 13, 255 |
3 | 13, 15, 13, 255 |
5 | 13, 5, 13, 85 |
13 | 13, 1, 13, 17 |
1, 1, 1, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 13 x 1 x 1 x 1 x 17 = 13260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13260
Therefore, the GCF of Fractions 72/52,82/60,83/13,87/255 is 1/13260
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 52,60,13,255 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(52,60,13,255) = 1
common factors(in case of two or more numbers have common factors) = 780
GCF(52,60,13,255) x common factors =1 x 780 = 780
LCM(52,60,13,255) = ( 52 × 60 × 13 × 255 ) / 780
LCM(52,60,13,255) = 10342800 / 780
LCM(52,60,13,255) = 13260
