Given numbers are 705, 731, 634, 243

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 731 are 17 x 43

Prime factors of 634 are 2 x 317

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 705, 731, 634, 243

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

Apply this formula for all numbers.

Step1:

LCM(705, 731) = 515355

GCD(705, 731) = ( 705 x 731 ) / 515355

= 705 / 731

= 705

Step2:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 705, 731, 634, 243 is 1
