Given numbers are 442, 755, 623, 680

The list of prime factors of all numbers are

Prime factors of 442 are 2 x 13 x 17

Prime factors of 755 are 5 x 151

Prime factors of 623 are 7 x 89

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 442, 755, 623, 680

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

Apply this formula for all numbers.

Step1:

LCM(442, 755) = 333710

GCD(442, 755) = ( 442 x 755 ) / 333710

= 442 / 755

= 442

Step2:

LCM(1, 623) = 623

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

= 1 / 623

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 442, 755, 623, 680 is 1
