Given numbers are 578, 554, 420, 536

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

Apply this formula for all numbers.

Step1:

LCM(578, 554) = 160106

GCD(578, 554) = ( 578 x 554 ) / 160106

= 578 / 554

= 578

Step2:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

Step3:

LCM(2, 536) = 536

GCD(2, 536) = ( 2 x 536 ) / 536

= 2 / 536

= 2

So, Greatest Common Divisor of 578, 554, 420, 536 is 2
