:1,811
Greatest Common Factor
We found the factors 912,811 . The biggest common factor number is the GCF number.
So the greatest common factor 912,811 is 1.
Lets's calculate LCM of 691,620
Given numbers has no common factors except 1. So, there LCM is their product i.e 428420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/428420
Therefore, the GCF of Fractions 912/691,811/620 is 1/428420
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 691,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(691,620) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(691,620) x common factors =1 x 1 = 1
LCM(691,620) = ( 691 × 620 ) / 1
LCM(691,620) = 428420 / 1
LCM(691,620) = 428420
