Given numbers are 805, 877, 980, 623

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 877 are 877

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 623 are 7 x 89

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

Given numbers are 805, 877, 980, 623

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

Apply this formula for all numbers.

Step1:

LCM(805, 877) = 705985

GCD(805, 877) = ( 805 x 877 ) / 705985

= 805 / 877

= 805

Step2:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

Step3:

LCM(1, 623) = 623

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

= 1 / 623

= 1

So, Greatest Common Divisor of 805, 877, 980, 623 is 1
