Given numbers are 429, 177, 639, 361

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

Apply this formula for all numbers.

Step1:

LCM(429, 177) = 25311

GCD(429, 177) = ( 429 x 177 ) / 25311

= 429 / 177

= 429

Step2:

LCM(3, 639) = 639

GCD(3, 639) = ( 3 x 639 ) / 639

= 3 / 639

= 3

Step3:

LCM(3, 361) = 1083

GCD(3, 361) = ( 3 x 361 ) / 1083

= 3 / 361

= 3

So, Greatest Common Divisor of 429, 177, 639, 361 is 1
