Given numbers are 643, 507, 636, 433

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

Apply this formula for all numbers.

Step1:

LCM(643, 507) = 326001

GCD(643, 507) = ( 643 x 507 ) / 326001

= 643 / 507

= 643

Step2:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

Step3:

LCM(1, 433) = 433

GCD(1, 433) = ( 1 x 433 ) / 433

= 1 / 433

= 1

So, Greatest Common Divisor of 643, 507, 636, 433 is 1
