Given numbers are 387, 429, 345, 452

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

Apply this formula for all numbers.

Step1:

LCM(387, 429) = 55341

GCD(387, 429) = ( 387 x 429 ) / 55341

= 387 / 429

= 387

Step2:

LCM(3, 345) = 345

GCD(3, 345) = ( 3 x 345 ) / 345

= 3 / 345

= 3

Step3:

LCM(3, 452) = 1356

GCD(3, 452) = ( 3 x 452 ) / 1356

= 3 / 452

= 3

So, Greatest Common Divisor of 387, 429, 345, 452 is 1
