:1,23
Now, list down the factors of 356
:1,2,4,89,178,356
Now, list down the factors of 781
:1,11,71,781
Greatest Common Factor
We found the factors 23,356,781 . The biggest common factor number is the GCF number.
So the greatest common factor 23,356,781 is 1.
Lets's calculate LCM of 17,70,842
2 | 17, 70, 842 |
17, 35, 421 |
∴ So the LCM of the given numbers is 2 x 17 x 35 x 421 = 500990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/500990
Therefore, the GCF of Fractions 23/17,356/70,781/842 is 1/500990
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 17,70,842 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,70,842) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(17,70,842) x common factors =1 x 2 = 2
LCM(17,70,842) = ( 17 × 70 × 842 ) / 2
LCM(17,70,842) = 1001980 / 2
LCM(17,70,842) = 500990
