Given numbers are 478, 227, 859, 990

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

Apply this formula for all numbers.

Step1:

LCM(478, 227) = 108506

GCD(478, 227) = ( 478 x 227 ) / 108506

= 478 / 227

= 478

Step2:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 478, 227, 859, 990 is 1
