Given numbers are 205, 156, 131, 154

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 131 are 131

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 205, 156, 131, 154

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

Apply this formula for all numbers.

Step1:

LCM(205, 156) = 31980

GCD(205, 156) = ( 205 x 156 ) / 31980

= 205 / 156

= 205

Step2:

LCM(1, 131) = 131

GCD(1, 131) = ( 1 x 131 ) / 131

= 1 / 131

= 1

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 205, 156, 131, 154 is 1
