Given numbers are 861, 770, 133, 156

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 133 are 7 x 19

Prime factors of 156 are 2 x 2 x 3 x 13

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

Given numbers are 861, 770, 133, 156

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

Apply this formula for all numbers.

Step1:

LCM(861, 770) = 94710

GCD(861, 770) = ( 861 x 770 ) / 94710

= 861 / 770

= 861

Step2:

LCM(7, 133) = 133

GCD(7, 133) = ( 7 x 133 ) / 133

= 7 / 133

= 7

Step3:

LCM(7, 156) = 1092

GCD(7, 156) = ( 7 x 156 ) / 1092

= 7 / 156

= 7

So, Greatest Common Divisor of 861, 770, 133, 156 is 1
