Given numbers are 825, 170, 845, 435

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

Apply this formula for all numbers.

Step1:

LCM(825, 170) = 28050

GCD(825, 170) = ( 825 x 170 ) / 28050

= 825 / 170

= 825

Step2:

LCM(5, 845) = 845

GCD(5, 845) = ( 5 x 845 ) / 845

= 5 / 845

= 5

Step3:

LCM(5, 435) = 435

GCD(5, 435) = ( 5 x 435 ) / 435

= 5 / 435

= 5

So, Greatest Common Divisor of 825, 170, 845, 435 is 5
