Given numbers are 156, 456, 696, 661

The list of prime factors of all numbers are

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

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

Prime factors of 661 are 661

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

Given numbers are 156, 456, 696, 661

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

Apply this formula for all numbers.

Step1:

LCM(156, 456) = 5928

GCD(156, 456) = ( 156 x 456 ) / 5928

= 156 / 456

= 156

Step2:

LCM(12, 696) = 696

GCD(12, 696) = ( 12 x 696 ) / 696

= 12 / 696

= 12

Step3:

LCM(12, 661) = 7932

GCD(12, 661) = ( 12 x 661 ) / 7932

= 12 / 661

= 12

So, Greatest Common Divisor of 156, 456, 696, 661 is 1
