Given numbers are 819, 189, 530, 670

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

Apply this formula for all numbers.

Step1:

LCM(819, 189) = 2457

GCD(819, 189) = ( 819 x 189 ) / 2457

= 819 / 189

= 819

Step2:

LCM(63, 530) = 33390

GCD(63, 530) = ( 63 x 530 ) / 33390

= 63 / 530

= 63

Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 819, 189, 530, 670 is 1
