Given numbers are 669, 870, 291, 206

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

Apply this formula for all numbers.

Step1:

LCM(669, 870) = 194010

GCD(669, 870) = ( 669 x 870 ) / 194010

= 669 / 870

= 669

Step2:

LCM(3, 291) = 291

GCD(3, 291) = ( 3 x 291 ) / 291

= 3 / 291

= 3

Step3:

LCM(3, 206) = 618

GCD(3, 206) = ( 3 x 206 ) / 618

= 3 / 206

= 3

So, Greatest Common Divisor of 669, 870, 291, 206 is 1
