Given numbers are 623, 508, 765, 406

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 508 are 2 x 2 x 127

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 623, 508, 765, 406

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

Apply this formula for all numbers.

Step1:

LCM(623, 508) = 316484

GCD(623, 508) = ( 623 x 508 ) / 316484

= 623 / 508

= 623

Step2:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

Step3:

LCM(1, 406) = 406

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

= 1 / 406

= 1

So, Greatest Common Divisor of 623, 508, 765, 406 is 1
