Given numbers are 505, 381, 133, 660

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 381 are 3 x 127

Prime factors of 133 are 7 x 19

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

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

Given numbers are 505, 381, 133, 660

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

Apply this formula for all numbers.

Step1:

LCM(505, 381) = 192405

GCD(505, 381) = ( 505 x 381 ) / 192405

= 505 / 381

= 505

Step2:

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

= 1 / 133

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 505, 381, 133, 660 is 1
