Given numbers are 438, 883, 840, 240

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 883 are 883

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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 438, 883, 840, 240

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

Apply this formula for all numbers.

Step1:

LCM(438, 883) = 386754

GCD(438, 883) = ( 438 x 883 ) / 386754

= 438 / 883

= 438

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 240) = 240

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

= 1 / 240

= 1

So, Greatest Common Divisor of 438, 883, 840, 240 is 1
