Given numbers are 407, 415, 690, 406

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 415 are 5 x 83

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

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 407, 415, 690, 406

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

Apply this formula for all numbers.

Step1:

LCM(407, 415) = 168905

GCD(407, 415) = ( 407 x 415 ) / 168905

= 407 / 415

= 407

Step2:

LCM(1, 690) = 690

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

= 1 / 690

= 1

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 407, 415, 690, 406 is 1
