Given numbers are 455, 968, 643, 879

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

Apply this formula for all numbers.

Step1:

LCM(455, 968) = 440440

GCD(455, 968) = ( 455 x 968 ) / 440440

= 455 / 968

= 455

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 879) = 879

GCD(1, 879) = ( 1 x 879 ) / 879

= 1 / 879

= 1

So, Greatest Common Divisor of 455, 968, 643, 879 is 1
