Given numbers are 730, 221, 475, 161

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 221 are 13 x 17

Prime factors of 475 are 5 x 5 x 19

Prime factors of 161 are 7 x 23

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

Given numbers are 730, 221, 475, 161

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

Apply this formula for all numbers.

Step1:

LCM(730, 221) = 161330

GCD(730, 221) = ( 730 x 221 ) / 161330

= 730 / 221

= 730

Step2:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 730, 221, 475, 161 is 1
