Given numbers are 478, 585, 79, 220

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

Apply this formula for all numbers.

Step1:

LCM(478, 585) = 279630

GCD(478, 585) = ( 478 x 585 ) / 279630

= 478 / 585

= 478

Step2:

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

= 1 / 79

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 478, 585, 79, 220 is 1
