Therefore, the GCF of 65/899,13/4420 is 13/3973580.
To find the highest common factor of 65,13, we have to find the factors of both numbers and list the highest common factor.
The factors of 65 are 1, 5, 13, 65
The factors of 13 are 1, 13
The HCF of 65,13 is 13.
Lets's calculate GCF of 65,13
13 | 65, 13 |
5, 1 |
∴ So the GCF of the given numbers is 13 = 13
Lets's calculate LCM of 899,4420
Given numbers has no common factors except 1. So, there LCM is their product i.e 3973580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/3973580
Therefore, the GCF of Fractions 65/899,13/4420 is 13/3973580
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 899,4420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(899,4420) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(899,4420) x common factors =1 x 1 = 1
LCM(899,4420) = ( 899 × 4420 ) / 1
LCM(899,4420) = 3973580 / 1
LCM(899,4420) = 3973580
