Given numbers are 198, 472, 69, 861

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

Apply this formula for all numbers.

Step1:

LCM(198, 472) = 46728

GCD(198, 472) = ( 198 x 472 ) / 46728

= 198 / 472

= 198

Step2:

LCM(2, 69) = 138

GCD(2, 69) = ( 2 x 69 ) / 138

= 2 / 69

= 2

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 198, 472, 69, 861 is 1
