Given numbers are 154, 861, 393, 365

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 861 are 3 x 7 x 41

Prime factors of 393 are 3 x 131

Prime factors of 365 are 5 x 73

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

Given numbers are 154, 861, 393, 365

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

Apply this formula for all numbers.

Step1:

LCM(154, 861) = 18942

GCD(154, 861) = ( 154 x 861 ) / 18942

= 154 / 861

= 154

Step2:

LCM(7, 393) = 2751

GCD(7, 393) = ( 7 x 393 ) / 2751

= 7 / 393

= 7

Step3:

LCM(1, 365) = 365

GCD(1, 365) = ( 1 x 365 ) / 365

= 1 / 365

= 1

So, Greatest Common Divisor of 154, 861, 393, 365 is 1
