Given numbers are 428, 766, 206, 556

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

Apply this formula for all numbers.

Step1:

LCM(428, 766) = 163924

GCD(428, 766) = ( 428 x 766 ) / 163924

= 428 / 766

= 428

Step2:

LCM(2, 206) = 206

GCD(2, 206) = ( 2 x 206 ) / 206

= 2 / 206

= 2

Step3:

LCM(2, 556) = 556

GCD(2, 556) = ( 2 x 556 ) / 556

= 2 / 556

= 2

So, Greatest Common Divisor of 428, 766, 206, 556 is 2
