Given numbers are 353, 372, 406, 640

The list of prime factors of all numbers are

Prime factors of 353 are 353

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 406 are 2 x 7 x 29

Prime factors of 640 are 2 x 2 x 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 353, 372, 406, 640

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

Apply this formula for all numbers.

Step1:

LCM(353, 372) = 131316

GCD(353, 372) = ( 353 x 372 ) / 131316

= 353 / 372

= 353

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 353, 372, 406, 640 is 1
