List of positive integer factors of 274 that divides 274 without a remainder.
1,2,137,274
Greatest Common Factor
We found the factors 306,441,274 . The biggest common factor number is the GCF number.
So the greatest common factor 306,441,274 is 1.
Lets's calculate LCM of 42,64,398
2 | 42, 64, 398 |
21, 32, 199 |
∴ So the LCM of the given numbers is 2 x 21 x 32 x 199 = 267456
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/267456
Therefore, the GCF of Fractions 306/42,441/64,274/398 is 1/267456
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 42,64,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,64,398) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(42,64,398) x common factors =2 x 2 = 4
LCM(42,64,398) = ( 42 × 64 × 398 ) / 4
LCM(42,64,398) = 1069824 / 4
LCM(42,64,398) = 267456
