Given numbers are 645, 303, 510, 765

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

Apply this formula for all numbers.

Step1:

LCM(645, 303) = 65145

GCD(645, 303) = ( 645 x 303 ) / 65145

= 645 / 303

= 645

Step2:

LCM(3, 510) = 510

GCD(3, 510) = ( 3 x 510 ) / 510

= 3 / 510

= 3

Step3:

LCM(3, 765) = 765

GCD(3, 765) = ( 3 x 765 ) / 765

= 3 / 765

= 3

So, Greatest Common Divisor of 645, 303, 510, 765 is 3
