Given numbers are 428, 212, 203, 302

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

Apply this formula for all numbers.

Step1:

LCM(428, 212) = 22684

GCD(428, 212) = ( 428 x 212 ) / 22684

= 428 / 212

= 428

Step2:

LCM(4, 203) = 812

GCD(4, 203) = ( 4 x 203 ) / 812

= 4 / 203

= 4

Step3:

LCM(1, 302) = 302

GCD(1, 302) = ( 1 x 302 ) / 302

= 1 / 302

= 1

So, Greatest Common Divisor of 428, 212, 203, 302 is 1
