Given numbers are 155, 999, 690, 511

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 999 are 3 x 3 x 3 x 37

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

Prime factors of 511 are 7 x 73

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

Given numbers are 155, 999, 690, 511

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

Apply this formula for all numbers.

Step1:

LCM(155, 999) = 154845

GCD(155, 999) = ( 155 x 999 ) / 154845

= 155 / 999

= 155

Step2:

LCM(1, 690) = 690

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

= 1 / 690

= 1

Step3:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

So, Greatest Common Divisor of 155, 999, 690, 511 is 1
