Given numbers are 861, 414, 122, 755

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 414 are 2 x 3 x 3 x 23

Prime factors of 122 are 2 x 61

Prime factors of 755 are 5 x 151

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

Given numbers are 861, 414, 122, 755

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

Apply this formula for all numbers.

Step1:

LCM(861, 414) = 118818

GCD(861, 414) = ( 861 x 414 ) / 118818

= 861 / 414

= 861

Step2:

LCM(3, 122) = 366

GCD(3, 122) = ( 3 x 122 ) / 366

= 3 / 122

= 3

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 861, 414, 122, 755 is 1
