Given numbers are 120, 635, 620, 208

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 635 are 5 x 127

Prime factors of 620 are 2 x 2 x 5 x 31

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

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

Given numbers are 120, 635, 620, 208

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

Apply this formula for all numbers.

Step1:

LCM(120, 635) = 15240

GCD(120, 635) = ( 120 x 635 ) / 15240

= 120 / 635

= 120

Step2:

LCM(5, 620) = 620

GCD(5, 620) = ( 5 x 620 ) / 620

= 5 / 620

= 5

Step3:

LCM(5, 208) = 1040

GCD(5, 208) = ( 5 x 208 ) / 1040

= 5 / 208

= 5

So, Greatest Common Divisor of 120, 635, 620, 208 is 1
