Given numbers are 823, 646, 230, 997

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

Apply this formula for all numbers.

Step1:

LCM(823, 646) = 531658

GCD(823, 646) = ( 823 x 646 ) / 531658

= 823 / 646

= 823

Step2:

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

= 1 / 230

= 1

Step3:

LCM(1, 997) = 997

GCD(1, 997) = ( 1 x 997 ) / 997

= 1 / 997

= 1

So, Greatest Common Divisor of 823, 646, 230, 997 is 1
