Given numbers are 181, 660, 145, 180

The list of prime factors of all numbers are

Prime factors of 181 are 181

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 145 are 5 x 29

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 181, 660, 145, 180

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

Apply this formula for all numbers.

Step1:

LCM(181, 660) = 119460

GCD(181, 660) = ( 181 x 660 ) / 119460

= 181 / 660

= 181

Step2:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 181, 660, 145, 180 is 1
