Given numbers are 651, 909, 187, 869

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

Apply this formula for all numbers.

Step1:

LCM(651, 909) = 197253

GCD(651, 909) = ( 651 x 909 ) / 197253

= 651 / 909

= 651

Step2:

LCM(3, 187) = 561

GCD(3, 187) = ( 3 x 187 ) / 561

= 3 / 187

= 3

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 651, 909, 187, 869 is 1
