Given numbers are 861, 155, 884, 851

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 155 are 5 x 31

Prime factors of 884 are 2 x 2 x 13 x 17

Prime factors of 851 are 23 x 37

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

Given numbers are 861, 155, 884, 851

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

Apply this formula for all numbers.

Step1:

LCM(861, 155) = 133455

GCD(861, 155) = ( 861 x 155 ) / 133455

= 861 / 155

= 861

Step2:

LCM(1, 884) = 884

GCD(1, 884) = ( 1 x 884 ) / 884

= 1 / 884

= 1

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 861, 155, 884, 851 is 1
