Given numbers are 987, 186, 469, 643

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

Apply this formula for all numbers.

Step1:

LCM(987, 186) = 61194

GCD(987, 186) = ( 987 x 186 ) / 61194

= 987 / 186

= 987

Step2:

LCM(3, 469) = 1407

GCD(3, 469) = ( 3 x 469 ) / 1407

= 3 / 469

= 3

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 987, 186, 469, 643 is 1
