Given numbers are 385, 656, 284, 240

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 284 are 2 x 2 x 71

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 385, 656, 284, 240

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

Apply this formula for all numbers.

Step1:

LCM(385, 656) = 252560

GCD(385, 656) = ( 385 x 656 ) / 252560

= 385 / 656

= 385

Step2:

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

= 1 / 284

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 385, 656, 284, 240 is 1
