Given numbers are 121, 305, 330, 785

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 305 are 5 x 61

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 785 are 5 x 157

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

Given numbers are 121, 305, 330, 785

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

Apply this formula for all numbers.

Step1:

LCM(121, 305) = 36905

GCD(121, 305) = ( 121 x 305 ) / 36905

= 121 / 305

= 121

Step2:

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

= 1 / 330

= 1

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 121, 305, 330, 785 is 1
