Given numbers are 215, 420, 834, 293

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 834 are 2 x 3 x 139

Prime factors of 293 are 293

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

Given numbers are 215, 420, 834, 293

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

Apply this formula for all numbers.

Step1:

LCM(215, 420) = 18060

GCD(215, 420) = ( 215 x 420 ) / 18060

= 215 / 420

= 215

Step2:

LCM(5, 834) = 4170

GCD(5, 834) = ( 5 x 834 ) / 4170

= 5 / 834

= 5

Step3:

LCM(1, 293) = 293

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

= 1 / 293

= 1

So, Greatest Common Divisor of 215, 420, 834, 293 is 1
