Given numbers are 428, 349, 180, 183

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

Apply this formula for all numbers.

Step1:

LCM(428, 349) = 149372

GCD(428, 349) = ( 428 x 349 ) / 149372

= 428 / 349

= 428

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 183) = 183

GCD(1, 183) = ( 1 x 183 ) / 183

= 1 / 183

= 1

So, Greatest Common Divisor of 428, 349, 180, 183 is 1
