Given numbers are 784, 220, 211, 449

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

Apply this formula for all numbers.

Step1:

LCM(784, 220) = 43120

GCD(784, 220) = ( 784 x 220 ) / 43120

= 784 / 220

= 784

Step2:

LCM(4, 211) = 844

GCD(4, 211) = ( 4 x 211 ) / 844

= 4 / 211

= 4

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 784, 220, 211, 449 is 1
