Given numbers are 454, 408, 887, 861

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

Apply this formula for all numbers.

Step1:

LCM(454, 408) = 92616

GCD(454, 408) = ( 454 x 408 ) / 92616

= 454 / 408

= 454

Step2:

LCM(2, 887) = 1774

GCD(2, 887) = ( 2 x 887 ) / 1774

= 2 / 887

= 2

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 454, 408, 887, 861 is 1
