Given numbers are 120, 651, 429, 345

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

Apply this formula for all numbers.

Step1:

LCM(120, 651) = 26040

GCD(120, 651) = ( 120 x 651 ) / 26040

= 120 / 651

= 120

Step2:

LCM(3, 429) = 429

GCD(3, 429) = ( 3 x 429 ) / 429

= 3 / 429

= 3

Step3:

LCM(3, 345) = 345

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

= 3 / 345

= 3

So, Greatest Common Divisor of 120, 651, 429, 345 is 3
