Given numbers are 491, 455, 521, 847

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

Apply this formula for all numbers.

Step1:

LCM(491, 455) = 223405

GCD(491, 455) = ( 491 x 455 ) / 223405

= 491 / 455

= 491

Step2:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

Step3:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

So, Greatest Common Divisor of 491, 455, 521, 847 is 1
