Given numbers are 491, 784, 247, 271

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

Apply this formula for all numbers.

Step1:

LCM(491, 784) = 384944

GCD(491, 784) = ( 491 x 784 ) / 384944

= 491 / 784

= 491

Step2:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

Step3:

LCM(1, 271) = 271

GCD(1, 271) = ( 1 x 271 ) / 271

= 1 / 271

= 1

So, Greatest Common Divisor of 491, 784, 247, 271 is 1
