Given numbers are 802, 389, 821, 260

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

Apply this formula for all numbers.

Step1:

LCM(802, 389) = 311978

GCD(802, 389) = ( 802 x 389 ) / 311978

= 802 / 389

= 802

Step2:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

Step3:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

So, Greatest Common Divisor of 802, 389, 821, 260 is 1
