Given numbers are 621, 540, 664, 160

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 621, 540, 664, 160

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

Apply this formula for all numbers.

Step1:

LCM(621, 540) = 12420

GCD(621, 540) = ( 621 x 540 ) / 12420

= 621 / 540

= 621

Step2:

LCM(27, 664) = 17928

GCD(27, 664) = ( 27 x 664 ) / 17928

= 27 / 664

= 27

Step3:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

So, Greatest Common Divisor of 621, 540, 664, 160 is 1
