Given numbers are 549, 402, 389, 113

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

Apply this formula for all numbers.

Step1:

LCM(549, 402) = 73566

GCD(549, 402) = ( 549 x 402 ) / 73566

= 549 / 402

= 549

Step2:

LCM(3, 389) = 1167

GCD(3, 389) = ( 3 x 389 ) / 1167

= 3 / 389

= 3

Step3:

LCM(1, 113) = 113

GCD(1, 113) = ( 1 x 113 ) / 113

= 1 / 113

= 1

So, Greatest Common Divisor of 549, 402, 389, 113 is 1
