Given numbers are 429, 639, 89, 197

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

Apply this formula for all numbers.

Step1:

LCM(429, 639) = 91377

GCD(429, 639) = ( 429 x 639 ) / 91377

= 429 / 639

= 429

Step2:

LCM(3, 89) = 267

GCD(3, 89) = ( 3 x 89 ) / 267

= 3 / 89

= 3

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 429, 639, 89, 197 is 1
