:1,2,4,5,10,13,20,26,52,65,130,260
Greatest Common Factor
We found the factors 73,417,260 . The biggest common factor number is the GCF number.
So the greatest common factor 73,417,260 is 1.
Lets's calculate LCM of 76,42,490
2 | 76, 42, 490 |
7 | 38, 21, 245 |
38, 3, 35 |
∴ So the LCM of the given numbers is 2 x 7 x 38 x 3 x 35 = 55860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/55860
Therefore, the GCF of Fractions 73/76,417/42,260/490 is 1/55860
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 76,42,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,42,490) = 2
common factors(in case of two or more numbers have common factors) = 14
GCF(76,42,490) x common factors =2 x 14 = 28
LCM(76,42,490) = ( 76 × 42 × 490 ) / 28
LCM(76,42,490) = 1564080 / 28
LCM(76,42,490) = 55860
