Lets's calculate LCM of 640,881
Given numbers has no common factors except 1. So, there LCM is their product i.e 563840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/563840
Therefore, the GCF of Fractions 378/640,143/881 is 1/563840
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 640,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,881) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(640,881) x common factors =1 x 1 = 1
LCM(640,881) = ( 640 × 881 ) / 1
LCM(640,881) = 563840 / 1
LCM(640,881) = 563840
