Given numbers are 525, 810, 126, 789

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

Apply this formula for all numbers.

Step1:

LCM(525, 810) = 28350

GCD(525, 810) = ( 525 x 810 ) / 28350

= 525 / 810

= 525

Step2:

LCM(15, 126) = 630

GCD(15, 126) = ( 15 x 126 ) / 630

= 15 / 126

= 15

Step3:

LCM(3, 789) = 789

GCD(3, 789) = ( 3 x 789 ) / 789

= 3 / 789

= 3

So, Greatest Common Divisor of 525, 810, 126, 789 is 3
