Given numbers are 205, 690, 496, 755

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

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

Prime factors of 496 are 2 x 2 x 2 x 2 x 31

Prime factors of 755 are 5 x 151

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

Given numbers are 205, 690, 496, 755

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

Apply this formula for all numbers.

Step1:

LCM(205, 690) = 28290

GCD(205, 690) = ( 205 x 690 ) / 28290

= 205 / 690

= 205

Step2:

LCM(5, 496) = 2480

GCD(5, 496) = ( 5 x 496 ) / 2480

= 5 / 496

= 5

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 205, 690, 496, 755 is 1
