Greatest Common Factor
We found the factors 85,45,47,92 . The biggest common factor number is the GCF number.
So the greatest common factor 85,45,47,92 is 1.
Lets's calculate LCM of 56,11,32,382
2 | 56, 11, 32, 382 |
2 | 28, 11, 16, 191 |
2 | 14, 11, 8, 191 |
7, 11, 4, 191 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 11 x 4 x 191 = 470624
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/470624
Therefore, the GCF of Fractions 85/56,45/11,47/32,92/382 is 1/470624
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 56,11,32,382 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,11,32,382) = 1
common factors(in case of two or more numbers have common factors) = 16
GCF(56,11,32,382) x common factors =1 x 16 = 16
LCM(56,11,32,382) = ( 56 × 11 × 32 × 382 ) / 16
LCM(56,11,32,382) = 7529984 / 16
LCM(56,11,32,382) = 470624
