Given numbers are 491, 424, 655, 571

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

Apply this formula for all numbers.

Step1:

LCM(491, 424) = 208184

GCD(491, 424) = ( 491 x 424 ) / 208184

= 491 / 424

= 491

Step2:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

Step3:

LCM(1, 571) = 571

GCD(1, 571) = ( 1 x 571 ) / 571

= 1 / 571

= 1

So, Greatest Common Divisor of 491, 424, 655, 571 is 1
