Given numbers are 906, 456, 20, 398

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

Apply this formula for all numbers.

Step1:

LCM(906, 456) = 68856

GCD(906, 456) = ( 906 x 456 ) / 68856

= 906 / 456

= 906

Step2:

LCM(6, 20) = 60

GCD(6, 20) = ( 6 x 20 ) / 60

= 6 / 20

= 6

Step3:

LCM(2, 398) = 398

GCD(2, 398) = ( 2 x 398 ) / 398

= 2 / 398

= 2

So, Greatest Common Divisor of 906, 456, 20, 398 is 2
