Given numbers are 406, 555, 130, 688

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 555 are 3 x 5 x 37

Prime factors of 130 are 2 x 5 x 13

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 406, 555, 130, 688

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

Apply this formula for all numbers.

Step1:

LCM(406, 555) = 225330

GCD(406, 555) = ( 406 x 555 ) / 225330

= 406 / 555

= 406

Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 406, 555, 130, 688 is 1
