Given numbers are 654, 806, 56, 470

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

Apply this formula for all numbers.

Step1:

LCM(654, 806) = 263562

GCD(654, 806) = ( 654 x 806 ) / 263562

= 654 / 806

= 654

Step2:

LCM(2, 56) = 56

GCD(2, 56) = ( 2 x 56 ) / 56

= 2 / 56

= 2

Step3:

LCM(2, 470) = 470

GCD(2, 470) = ( 2 x 470 ) / 470

= 2 / 470

= 2

So, Greatest Common Divisor of 654, 806, 56, 470 is 2
