Given numbers are 108, 660, 441, 145

The list of prime factors of all numbers are

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

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

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 145 are 5 x 29

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

Given numbers are 108, 660, 441, 145

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

Apply this formula for all numbers.

Step1:

LCM(108, 660) = 5940

GCD(108, 660) = ( 108 x 660 ) / 5940

= 108 / 660

= 108

Step2:

LCM(12, 441) = 1764

GCD(12, 441) = ( 12 x 441 ) / 1764

= 12 / 441

= 12

Step3:

LCM(3, 145) = 435

GCD(3, 145) = ( 3 x 145 ) / 435

= 3 / 145

= 3

So, Greatest Common Divisor of 108, 660, 441, 145 is 1
