Given numbers are 131, 644, 400, 304

The list of prime factors of all numbers are

Prime factors of 131 are 131

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

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

Given numbers are 131, 644, 400, 304

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(131, 644) = 84364

GCD(131, 644) = ( 131 x 644 ) / 84364

= 131 / 644

= 131

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 304) = 304

GCD(1, 304) = ( 1 x 304 ) / 304

= 1 / 304

= 1

So, Greatest Common Divisor of 131, 644, 400, 304 is 1
