Given numbers are 861, 145, 734, 956

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 145 are 5 x 29

Prime factors of 734 are 2 x 367

Prime factors of 956 are 2 x 2 x 239

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

Given numbers are 861, 145, 734, 956

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

Apply this formula for all numbers.

Step1:

LCM(861, 145) = 124845

GCD(861, 145) = ( 861 x 145 ) / 124845

= 861 / 145

= 861

Step2:

LCM(1, 734) = 734

GCD(1, 734) = ( 1 x 734 ) / 734

= 1 / 734

= 1

Step3:

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

= 1 / 956

= 1

So, Greatest Common Divisor of 861, 145, 734, 956 is 1
