So the greatest common factor 407,420 is 1.
Lets's calculate LCM of 799,700
Given numbers has no common factors except 1. So, there LCM is their product i.e 559300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/559300
Therefore, the GCF of Fractions 407/799,420/700 is 1/559300
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 799,700 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(799,700) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(799,700) x common factors =1 x 1 = 1
LCM(799,700) = ( 799 × 700 ) / 1
LCM(799,700) = 559300 / 1
LCM(799,700) = 559300
