Given numbers are 823, 639, 878, 189

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

Apply this formula for all numbers.

Step1:

LCM(823, 639) = 525897

GCD(823, 639) = ( 823 x 639 ) / 525897

= 823 / 639

= 823

Step2:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 823, 639, 878, 189 is 1
