Given numbers are 423, 678, 556, 490

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

Apply this formula for all numbers.

Step1:

LCM(423, 678) = 95598

GCD(423, 678) = ( 423 x 678 ) / 95598

= 423 / 678

= 423

Step2:

LCM(3, 556) = 1668

GCD(3, 556) = ( 3 x 556 ) / 1668

= 3 / 556

= 3

Step3:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 423, 678, 556, 490 is 1
