Given numbers are 545, 455, 949, 911

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

Apply this formula for all numbers.

Step1:

LCM(545, 455) = 49595

GCD(545, 455) = ( 545 x 455 ) / 49595

= 545 / 455

= 545

Step2:

LCM(5, 949) = 4745

GCD(5, 949) = ( 5 x 949 ) / 4745

= 5 / 949

= 5

Step3:

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

= 1 / 911

= 1

So, Greatest Common Divisor of 545, 455, 949, 911 is 1
