Given numbers are 208, 155, 390, 652

The list of prime factors of all numbers are

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 155 are 5 x 31

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 652 are 2 x 2 x 163

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

Given numbers are 208, 155, 390, 652

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

Apply this formula for all numbers.

Step1:

LCM(208, 155) = 32240

GCD(208, 155) = ( 208 x 155 ) / 32240

= 208 / 155

= 208

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

= 1 / 652

= 1

So, Greatest Common Divisor of 208, 155, 390, 652 is 1
