So the greatest common factor 822,421 is 1.
Lets's calculate LCM of 174,372
2 | 174, 372 |
3 | 87, 186 |
29, 62 |
∴ So the LCM of the given numbers is 2 x 3 x 29 x 62 = 10788
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10788
Therefore, the GCF of Fractions 822/174,421/372 is 1/10788
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 174,372 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(174,372) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(174,372) x common factors =6 x 1 = 6
LCM(174,372) = ( 174 × 372 ) / 6
LCM(174,372) = 64728 / 6
LCM(174,372) = 10788
