So the greatest common factor 81,26,980 is 1.
Lets's calculate LCM of 498,485,694
2 | 498, 485, 694 |
249, 485, 347 |
∴ So the LCM of the given numbers is 2 x 249 x 485 x 347 = 83810910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/83810910
Therefore, the GCF of Fractions 81/498,26/485,980/694 is 1/83810910
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 498,485,694 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(498,485,694) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(498,485,694) x common factors =1 x 2 = 2
LCM(498,485,694) = ( 498 × 485 × 694 ) / 2
LCM(498,485,694) = 167621820 / 2
LCM(498,485,694) = 83810910
