Given numbers are 455, 411, 372, 393

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 411 are 3 x 137

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

Prime factors of 393 are 3 x 131

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

Given numbers are 455, 411, 372, 393

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

Apply this formula for all numbers.

Step1:

LCM(455, 411) = 187005

GCD(455, 411) = ( 455 x 411 ) / 187005

= 455 / 411

= 455

Step2:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 455, 411, 372, 393 is 1
