Given numbers are 434, 861, 775, 240

The list of prime factors of all numbers are

Prime factors of 434 are 2 x 7 x 31

Prime factors of 861 are 3 x 7 x 41

Prime factors of 775 are 5 x 5 x 31

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 434, 861, 775, 240

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

Apply this formula for all numbers.

Step1:

LCM(434, 861) = 53382

GCD(434, 861) = ( 434 x 861 ) / 53382

= 434 / 861

= 434

Step2:

LCM(7, 775) = 5425

GCD(7, 775) = ( 7 x 775 ) / 5425

= 7 / 775

= 7

Step3:

LCM(1, 240) = 240

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

= 1 / 240

= 1

So, Greatest Common Divisor of 434, 861, 775, 240 is 1
