Given numbers are 861, 683, 669, 240

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 683 are 683

Prime factors of 669 are 3 x 223

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 861, 683, 669, 240

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

Apply this formula for all numbers.

Step1:

LCM(861, 683) = 588063

GCD(861, 683) = ( 861 x 683 ) / 588063

= 861 / 683

= 861

Step2:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

Step3:

LCM(1, 240) = 240

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

= 1 / 240

= 1

So, Greatest Common Divisor of 861, 683, 669, 240 is 1
