Given numbers are 784, 163, 225, 399

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

Apply this formula for all numbers.

Step1:

LCM(784, 163) = 127792

GCD(784, 163) = ( 784 x 163 ) / 127792

= 784 / 163

= 784

Step2:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 784, 163, 225, 399 is 1
