We found the divisors of 248, 505, 15, 610 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 248, 505, 15, 610 is 1.

Therefore, GCD of numbers 248, 505, 15, 610 is 1

Given Input Data is 248, 505, 15, 610

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 248 is 2 x 2 x 2 x 31

Prime Factorization of 505 is 5 x 101

Prime Factorization of 15 is 3 x 5

Prime Factorization of 610 is 2 x 5 x 61

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(248, 505) = 125240

GCD(248, 505) = ( 248 x 505 ) / 125240

GCD(248, 505) = 125240 / 125240

GCD(248, 505) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 610

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

GCD(1, 610) = 610 / 610

GCD(1, 610) = 1

GCD of 248, 505, 15, 610 is 1
