Given numbers are 475, 690, 938, 210

The list of prime factors of all numbers are

Prime factors of 475 are 5 x 5 x 19

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

Prime factors of 938 are 2 x 7 x 67

Prime factors of 210 are 2 x 3 x 5 x 7

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

Given numbers are 475, 690, 938, 210

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

Apply this formula for all numbers.

Step1:

LCM(475, 690) = 65550

GCD(475, 690) = ( 475 x 690 ) / 65550

= 475 / 690

= 475

Step2:

LCM(5, 938) = 4690

GCD(5, 938) = ( 5 x 938 ) / 4690

= 5 / 938

= 5

Step3:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 475, 690, 938, 210 is 1
