Given numbers are 406, 978, 428, 888

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

Apply this formula for all numbers.

Step1:

LCM(406, 978) = 198534

GCD(406, 978) = ( 406 x 978 ) / 198534

= 406 / 978

= 406

Step2:

LCM(2, 428) = 428

GCD(2, 428) = ( 2 x 428 ) / 428

= 2 / 428

= 2

Step3:

LCM(2, 888) = 888

GCD(2, 888) = ( 2 x 888 ) / 888

= 2 / 888

= 2

So, Greatest Common Divisor of 406, 978, 428, 888 is 2
