Given numbers are 478, 779, 579, 555

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

Apply this formula for all numbers.

Step1:

LCM(478, 779) = 372362

GCD(478, 779) = ( 478 x 779 ) / 372362

= 478 / 779

= 478

Step2:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1

Step3:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 478, 779, 579, 555 is 1
