Greatest Common Factor
We found the factors 905,643 . The biggest common factor number is the GCF number.
So the greatest common factor 905,643 is 1.
Lets's calculate LCM of 803,863
Given numbers has no common factors except 1. So, there LCM is their product i.e 692989
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/692989
Therefore, the GCF of Fractions 905/803,643/863 is 1/692989
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 803,863 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(803,863) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(803,863) x common factors =1 x 1 = 1
LCM(803,863) = ( 803 × 863 ) / 1
LCM(803,863) = 692989 / 1
LCM(803,863) = 692989
