Given numbers are 669, 651, 842

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

Apply this formula for all numbers.

Step1:

LCM(669, 651) = 145173

GCD(669, 651) = ( 669 x 651 ) / 145173

= 669 / 651

= 669

Step2:

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

= 3 / 842

= 3

So, Greatest Common Divisor of 669, 651, 842 is 1
