Given numbers are 643, 393, 377, 929

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

Apply this formula for all numbers.

Step1:

LCM(643, 393) = 252699

GCD(643, 393) = ( 643 x 393 ) / 252699

= 643 / 393

= 643

Step2:

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

= 1 / 377

= 1

Step3:

LCM(1, 929) = 929

GCD(1, 929) = ( 1 x 929 ) / 929

= 1 / 929

= 1

So, Greatest Common Divisor of 643, 393, 377, 929 is 1
