Given numbers are 195, 210, 630, 624

The list of prime factors of all numbers are

Prime factors of 195 are 3 x 5 x 13

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

The highest common occurrence is 3¹

Therefore, GCD of 195, 210, 630, 624 is 3.

Given numbers are 195, 210, 630, 624

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

Apply this formula for all numbers.

Step1:

LCM(195, 210) = 2730

GCD(195, 210) = ( 195 x 210 ) / 2730

= 195 / 210

= 195

Step2:

LCM(15, 630) = 630

GCD(15, 630) = ( 15 x 630 ) / 630

= 15 / 630

= 15

Step3:

LCM(15, 624) = 3120

GCD(15, 624) = ( 15 x 624 ) / 3120

= 15 / 624

= 15

So, Greatest Common Divisor of 195, 210, 630, 624 is 3
