Given numbers are 861, 493, 649, 486

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

Apply this formula for all numbers.

Step1:

LCM(861, 493) = 424473

GCD(861, 493) = ( 861 x 493 ) / 424473

= 861 / 493

= 861

Step2:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 861, 493, 649, 486 is 1
