Given numbers are 549, 915, 165, 947

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

Apply this formula for all numbers.

Step1:

LCM(549, 915) = 2745

GCD(549, 915) = ( 549 x 915 ) / 2745

= 549 / 915

= 549

Step2:

LCM(183, 165) = 10065

GCD(183, 165) = ( 183 x 165 ) / 10065

= 183 / 165

= 183

Step3:

LCM(3, 947) = 2841

GCD(3, 947) = ( 3 x 947 ) / 2841

= 3 / 947

= 3

So, Greatest Common Divisor of 549, 915, 165, 947 is 1
