Given numbers are 802, 872, 815, 669

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

Apply this formula for all numbers.

Step1:

LCM(802, 872) = 349672

GCD(802, 872) = ( 802 x 872 ) / 349672

= 802 / 872

= 802

Step2:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

Step3:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 802, 872, 815, 669 is 1
