Lets's calculate LCM of 55,42,670
2 | 55, 42, 670 |
5 | 55, 21, 335 |
11, 21, 67 |
∴ So the LCM of the given numbers is 2 x 5 x 11 x 21 x 67 = 154770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/154770
Therefore, the GCF of Fractions 80/55,960/42,577/670 is 1/154770
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 55,42,670 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,42,670) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(55,42,670) x common factors =1 x 10 = 10
LCM(55,42,670) = ( 55 × 42 × 670 ) / 10
LCM(55,42,670) = 1547700 / 10
LCM(55,42,670) = 154770
