Given numbers are 478, 320, 431, 906

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

Apply this formula for all numbers.

Step1:

LCM(478, 320) = 76480

GCD(478, 320) = ( 478 x 320 ) / 76480

= 478 / 320

= 478

Step2:

LCM(2, 431) = 862

GCD(2, 431) = ( 2 x 431 ) / 862

= 2 / 431

= 2

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 478, 320, 431, 906 is 1
