So the greatest common factor 849,280 is 1.
Lets's calculate LCM of 420,551
Given numbers has no common factors except 1. So, there LCM is their product i.e 231420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/231420
Therefore, the GCF of Fractions 849/420,280/551 is 1/231420
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 420,551 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,551) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(420,551) x common factors =1 x 1 = 1
LCM(420,551) = ( 420 × 551 ) / 1
LCM(420,551) = 231420 / 1
LCM(420,551) = 231420
