GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 645) = 4515
GCD(105, 645) = ( 105 x 645 ) / 4515
= 105 / 645
= 105
Step2:
LCM(15, 675) = 675
GCD(15, 675) = ( 15 x 675 ) / 675
= 15 / 675
= 15
Step3:
LCM(15, 519) = 2595
GCD(15, 519) = ( 15 x 519 ) / 2595
= 15 / 519
= 15
So, Greatest Common Divisor of 105, 645, 675, 519 is 3
