Given numbers are 449, 120, 482, 821

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

Apply this formula for all numbers.

Step1:

LCM(449, 120) = 53880

GCD(449, 120) = ( 449 x 120 ) / 53880

= 449 / 120

= 449

Step2:

LCM(1, 482) = 482

GCD(1, 482) = ( 1 x 482 ) / 482

= 1 / 482

= 1

Step3:

LCM(1, 821) = 821

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

= 1 / 821

= 1

So, Greatest Common Divisor of 449, 120, 482, 821 is 1
