Given numbers are 665, 230, 690, 358

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 230 are 2 x 5 x 23

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 358 are 2 x 179

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

Given numbers are 665, 230, 690, 358

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

Apply this formula for all numbers.

Step1:

LCM(665, 230) = 30590

GCD(665, 230) = ( 665 x 230 ) / 30590

= 665 / 230

= 665

Step2:

LCM(5, 690) = 690

GCD(5, 690) = ( 5 x 690 ) / 690

= 5 / 690

= 5

Step3:

LCM(5, 358) = 1790

GCD(5, 358) = ( 5 x 358 ) / 1790

= 5 / 358

= 5

So, Greatest Common Divisor of 665, 230, 690, 358 is 1
