Given numbers are 273, 422, 840, 747

The list of prime factors of all numbers are

Prime factors of 273 are 3 x 7 x 13

Prime factors of 422 are 2 x 211

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

Prime factors of 747 are 3 x 3 x 83

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

Given numbers are 273, 422, 840, 747

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

Apply this formula for all numbers.

Step1:

LCM(273, 422) = 115206

GCD(273, 422) = ( 273 x 422 ) / 115206

= 273 / 422

= 273

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

So, Greatest Common Divisor of 273, 422, 840, 747 is 1
