So the greatest common factor 172,1569 is 1.
Lets's calculate LCM of 990,253
11 | 990, 253 |
90, 23 |
∴ So the LCM of the given numbers is 11 x 90 x 23 = 22770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/22770
Therefore, the GCF of Fractions 172/990,1569/253 is 1/22770
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 990,253 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(990,253) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(990,253) x common factors =11 x 1 = 11
LCM(990,253) = ( 990 × 253 ) / 11
LCM(990,253) = 250470 / 11
LCM(990,253) = 22770
