Given numbers are 140, 664, 432, 491

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

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

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 491 are 491

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

Given numbers are 140, 664, 432, 491

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

Apply this formula for all numbers.

Step1:

LCM(140, 664) = 23240

GCD(140, 664) = ( 140 x 664 ) / 23240

= 140 / 664

= 140

Step2:

LCM(4, 432) = 432

GCD(4, 432) = ( 4 x 432 ) / 432

= 4 / 432

= 4

Step3:

LCM(4, 491) = 1964

GCD(4, 491) = ( 4 x 491 ) / 1964

= 4 / 491

= 4

So, Greatest Common Divisor of 140, 664, 432, 491 is 1
