Given numbers are 820, 909, 437

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

Apply this formula for all numbers.

Step1:

LCM(820, 909) = 745380

GCD(820, 909) = ( 820 x 909 ) / 745380

= 820 / 909

= 820

Step2:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 820, 909, 437 is 1
