Given numbers are 481, 855, 55, 144

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

Apply this formula for all numbers.

Step1:

LCM(481, 855) = 411255

GCD(481, 855) = ( 481 x 855 ) / 411255

= 481 / 855

= 481

Step2:

LCM(1, 55) = 55

GCD(1, 55) = ( 1 x 55 ) / 55

= 1 / 55

= 1

Step3:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

So, Greatest Common Divisor of 481, 855, 55, 144 is 1
