Given numbers are 402, 730, 478

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

Apply this formula for all numbers.

Step1:

LCM(402, 730) = 146730

GCD(402, 730) = ( 402 x 730 ) / 146730

= 402 / 730

= 402

Step2:

LCM(2, 478) = 478

GCD(2, 478) = ( 2 x 478 ) / 478

= 2 / 478

= 2

So, Greatest Common Divisor of 402, 730, 478 is 2
