Given numbers are 730, 668, 917, 391

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 668 are 2 x 2 x 167

Prime factors of 917 are 7 x 131

Prime factors of 391 are 17 x 23

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

Given numbers are 730, 668, 917, 391

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

Apply this formula for all numbers.

Step1:

LCM(730, 668) = 243820

GCD(730, 668) = ( 730 x 668 ) / 243820

= 730 / 668

= 730

Step2:

LCM(2, 917) = 1834

GCD(2, 917) = ( 2 x 917 ) / 1834

= 2 / 917

= 2

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 730, 668, 917, 391 is 1
