Given numbers are 423, 480, 948, 643

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

Apply this formula for all numbers.

Step1:

LCM(423, 480) = 67680

GCD(423, 480) = ( 423 x 480 ) / 67680

= 423 / 480

= 423

Step2:

LCM(3, 948) = 948

GCD(3, 948) = ( 3 x 948 ) / 948

= 3 / 948

= 3

Step3:

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

= 3 / 643

= 3

So, Greatest Common Divisor of 423, 480, 948, 643 is 1
