Given numbers are 455, 381, 623, 716

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 381 are 3 x 127

Prime factors of 623 are 7 x 89

Prime factors of 716 are 2 x 2 x 179

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

Given numbers are 455, 381, 623, 716

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

Apply this formula for all numbers.

Step1:

LCM(455, 381) = 173355

GCD(455, 381) = ( 455 x 381 ) / 173355

= 455 / 381

= 455

Step2:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

Step3:

LCM(1, 716) = 716

GCD(1, 716) = ( 1 x 716 ) / 716

= 1 / 716

= 1

So, Greatest Common Divisor of 455, 381, 623, 716 is 1
