Given numbers are 663, 802, 927, 821

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

Apply this formula for all numbers.

Step1:

LCM(663, 802) = 531726

GCD(663, 802) = ( 663 x 802 ) / 531726

= 663 / 802

= 663

Step2:

LCM(1, 927) = 927

GCD(1, 927) = ( 1 x 927 ) / 927

= 1 / 927

= 1

Step3:

LCM(1, 821) = 821

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

= 1 / 821

= 1

So, Greatest Common Divisor of 663, 802, 927, 821 is 1
