Lets's calculate LCM of 525,992
Given numbers has no common factors except 1. So, there LCM is their product i.e 520800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/520800
Therefore, the GCF of Fractions 639/525,575/992 is 1/520800
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 525,992 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(525,992) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(525,992) x common factors =1 x 1 = 1
LCM(525,992) = ( 525 × 992 ) / 1
LCM(525,992) = 520800 / 1
LCM(525,992) = 520800
