Given numbers are 239, 217, 580, 840

The list of prime factors of all numbers are

Prime factors of 239 are 239

Prime factors of 217 are 7 x 31

Prime factors of 580 are 2 x 2 x 5 x 29

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 239, 217, 580, 840

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

Apply this formula for all numbers.

Step1:

LCM(239, 217) = 51863

GCD(239, 217) = ( 239 x 217 ) / 51863

= 239 / 217

= 239

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 239, 217, 580, 840 is 1
