Given numbers are 861, 994, 765, 145

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 994 are 2 x 7 x 71

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

Prime factors of 145 are 5 x 29

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

Given numbers are 861, 994, 765, 145

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

Apply this formula for all numbers.

Step1:

LCM(861, 994) = 122262

GCD(861, 994) = ( 861 x 994 ) / 122262

= 861 / 994

= 861

Step2:

LCM(7, 765) = 5355

GCD(7, 765) = ( 7 x 765 ) / 5355

= 7 / 765

= 7

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 861, 994, 765, 145 is 1
