So the greatest common factor 84,54,353 is 1.
Lets's calculate LCM of 429,177,281
3 | 429, 177, 281 |
143, 59, 281 |
∴ So the LCM of the given numbers is 3 x 143 x 59 x 281 = 7112391
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7112391
Therefore, the GCF of Fractions 84/429,54/177,353/281 is 1/7112391
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 429,177,281 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(429,177,281) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(429,177,281) x common factors =1 x 3 = 3
LCM(429,177,281) = ( 429 × 177 × 281 ) / 3
LCM(429,177,281) = 21337173 / 3
LCM(429,177,281) = 7112391
