So the greatest common factor 7,77,55,291 is 1.
Lets's calculate LCM of 66,28,528,465
2 | 66, 28, 528, 465 |
2 | 33, 14, 264, 465 |
3 | 33, 7, 132, 465 |
11 | 11, 7, 44, 155 |
1, 7, 4, 155 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 11 x 1 x 7 x 4 x 155 = 572880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/572880
Therefore, the GCF of Fractions 7/66,77/28,55/528,291/465 is 1/572880
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 66,28,528,465 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(66,28,528,465) = 1
common factors(in case of two or more numbers have common factors) = 792
GCF(66,28,528,465) x common factors =1 x 792 = 792
LCM(66,28,528,465) = ( 66 × 28 × 528 × 465 ) / 792
LCM(66,28,528,465) = 453720960 / 792
LCM(66,28,528,465) = 572880
