Given numbers are 669, 291, 801, 810

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

Apply this formula for all numbers.

Step1:

LCM(669, 291) = 64893

GCD(669, 291) = ( 669 x 291 ) / 64893

= 669 / 291

= 669

Step2:

LCM(3, 801) = 801

GCD(3, 801) = ( 3 x 801 ) / 801

= 3 / 801

= 3

Step3:

LCM(3, 810) = 810

GCD(3, 810) = ( 3 x 810 ) / 810

= 3 / 810

= 3

So, Greatest Common Divisor of 669, 291, 801, 810 is 3
