Given numbers are 218, 383, 429, 840

The list of prime factors of all numbers are

Prime factors of 218 are 2 x 109

Prime factors of 383 are 383

Prime factors of 429 are 3 x 11 x 13

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

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

Given numbers are 218, 383, 429, 840

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

Apply this formula for all numbers.

Step1:

LCM(218, 383) = 83494

GCD(218, 383) = ( 218 x 383 ) / 83494

= 218 / 383

= 218

Step2:

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

= 1 / 429

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 218, 383, 429, 840 is 1
