Given numbers are 821, 408, 281, 282

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

Apply this formula for all numbers.

Step1:

LCM(821, 408) = 334968

GCD(821, 408) = ( 821 x 408 ) / 334968

= 821 / 408

= 821

Step2:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

Step3:

LCM(1, 282) = 282

GCD(1, 282) = ( 1 x 282 ) / 282

= 1 / 282

= 1

So, Greatest Common Divisor of 821, 408, 281, 282 is 1
