Greatest Common Factor
We found the factors 92,39,99,61 . The biggest common factor number is the GCF number.
So the greatest common factor 92,39,99,61 is 1.
Lets's calculate LCM of 56,23,49,940
2 | 56, 23, 49, 940 |
2 | 28, 23, 49, 470 |
7 | 14, 23, 49, 235 |
2, 23, 7, 235 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 2 x 23 x 7 x 235 = 2118760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2118760
Therefore, the GCF of Fractions 92/56,39/23,99/49,61/940 is 1/2118760
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 56,23,49,940 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,23,49,940) = 1
common factors(in case of two or more numbers have common factors) = 28
GCF(56,23,49,940) x common factors =1 x 28 = 28
LCM(56,23,49,940) = ( 56 × 23 × 49 × 940 ) / 28
LCM(56,23,49,940) = 59325280 / 28
LCM(56,23,49,940) = 2118760
