Given numbers are 840, 722, 205, 293

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 722 are 2 x 19 x 19

Prime factors of 205 are 5 x 41

Prime factors of 293 are 293

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

Given numbers are 840, 722, 205, 293

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

Apply this formula for all numbers.

Step1:

LCM(840, 722) = 303240

GCD(840, 722) = ( 840 x 722 ) / 303240

= 840 / 722

= 840

Step2:

LCM(2, 205) = 410

GCD(2, 205) = ( 2 x 205 ) / 410

= 2 / 205

= 2

Step3:

LCM(1, 293) = 293

GCD(1, 293) = ( 1 x 293 ) / 293

= 1 / 293

= 1

So, Greatest Common Divisor of 840, 722, 205, 293 is 1
