Lets's calculate LCM of 4030,1772
2 | 4030, 1772 |
2015, 886 |
∴ So the LCM of the given numbers is 2 x 2015 x 886 = 3570580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/3570580
Therefore, the GCF of Fractions 810/4030,865/1772 is 5/3570580
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 4030,1772 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(4030,1772) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(4030,1772) x common factors =2 x 1 = 2
LCM(4030,1772) = ( 4030 × 1772 ) / 2
LCM(4030,1772) = 7141160 / 2
LCM(4030,1772) = 3570580
