Given numbers are 429, 221, 178, 974

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

Apply this formula for all numbers.

Step1:

LCM(429, 221) = 7293

GCD(429, 221) = ( 429 x 221 ) / 7293

= 429 / 221

= 429

Step2:

LCM(13, 178) = 2314

GCD(13, 178) = ( 13 x 178 ) / 2314

= 13 / 178

= 13

Step3:

LCM(1, 974) = 974

GCD(1, 974) = ( 1 x 974 ) / 974

= 1 / 974

= 1

So, Greatest Common Divisor of 429, 221, 178, 974 is 1
