Given numbers are 387, 784, 184, 221

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

Apply this formula for all numbers.

Step1:

LCM(387, 784) = 303408

GCD(387, 784) = ( 387 x 784 ) / 303408

= 387 / 784

= 387

Step2:

LCM(1, 184) = 184

GCD(1, 184) = ( 1 x 184 ) / 184

= 1 / 184

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 387, 784, 184, 221 is 1
