Given numbers are 928, 628, 643, 878

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

Apply this formula for all numbers.

Step1:

LCM(928, 628) = 145696

GCD(928, 628) = ( 928 x 628 ) / 145696

= 928 / 628

= 928

Step2:

LCM(4, 643) = 2572

GCD(4, 643) = ( 4 x 643 ) / 2572

= 4 / 643

= 4

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 928, 628, 643, 878 is 1
