Given numbers are 427, 755, 336, 690

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 755 are 5 x 151

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

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

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

Given numbers are 427, 755, 336, 690

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

Apply this formula for all numbers.

Step1:

LCM(427, 755) = 322385

GCD(427, 755) = ( 427 x 755 ) / 322385

= 427 / 755

= 427

Step2:

LCM(1, 336) = 336

GCD(1, 336) = ( 1 x 336 ) / 336

= 1 / 336

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 427, 755, 336, 690 is 1
