Given numbers are 458, 220, 909, 578

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

Apply this formula for all numbers.

Step1:

LCM(458, 220) = 50380

GCD(458, 220) = ( 458 x 220 ) / 50380

= 458 / 220

= 458

Step2:

LCM(2, 909) = 1818

GCD(2, 909) = ( 2 x 909 ) / 1818

= 2 / 909

= 2

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 458, 220, 909, 578 is 1
