Given numbers are 428, 426, 30, 919

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

Apply this formula for all numbers.

Step1:

LCM(428, 426) = 91164

GCD(428, 426) = ( 428 x 426 ) / 91164

= 428 / 426

= 428

Step2:

LCM(2, 30) = 30

GCD(2, 30) = ( 2 x 30 ) / 30

= 2 / 30

= 2

Step3:

LCM(2, 919) = 1838

GCD(2, 919) = ( 2 x 919 ) / 1838

= 2 / 919

= 2

So, Greatest Common Divisor of 428, 426, 30, 919 is 1
