Given numbers are 820, 450, 430

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

Apply this formula for all numbers.

Step1:

LCM(820, 450) = 36900

GCD(820, 450) = ( 820 x 450 ) / 36900

= 820 / 450

= 820

Step2:

LCM(10, 430) = 430

GCD(10, 430) = ( 10 x 430 ) / 430

= 10 / 430

= 10

So, Greatest Common Divisor of 820, 450, 430 is 10
