Given numbers are 840, 579, 918, 247

The list of prime factors of all numbers are

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

Prime factors of 579 are 3 x 193

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

Prime factors of 247 are 13 x 19

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

Given numbers are 840, 579, 918, 247

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

Apply this formula for all numbers.

Step1:

LCM(840, 579) = 162120

GCD(840, 579) = ( 840 x 579 ) / 162120

= 840 / 579

= 840

Step2:

LCM(3, 918) = 918

GCD(3, 918) = ( 3 x 918 ) / 918

= 3 / 918

= 3

Step3:

LCM(3, 247) = 741

GCD(3, 247) = ( 3 x 247 ) / 741

= 3 / 247

= 3

So, Greatest Common Divisor of 840, 579, 918, 247 is 1
