1,5,25
Greatest Common Factor
We found the factors 68,60,70,25 . The biggest common factor number is the GCF number.
So the greatest common factor 68,60,70,25 is 1.
Lets's calculate LCM of 77,32,33,88
2 | 77, 32, 33, 88 |
2 | 77, 16, 33, 44 |
2 | 77, 8, 33, 22 |
11 | 77, 4, 33, 11 |
7, 4, 3, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 11 x 7 x 4 x 3 x 1 = 7392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7392
Therefore, the GCF of Fractions 68/77,60/32,70/33,25/88 is 1/7392
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 77,32,33,88 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,32,33,88) = 1
common factors(in case of two or more numbers have common factors) = 968
GCF(77,32,33,88) x common factors =1 x 968 = 968
LCM(77,32,33,88) = ( 77 × 32 × 33 × 88 ) / 968
LCM(77,32,33,88) = 7155456 / 968
LCM(77,32,33,88) = 7392
