Given numbers are 163, 438, 440, 853

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

Apply this formula for all numbers.

Step1:

LCM(163, 438) = 71394

GCD(163, 438) = ( 163 x 438 ) / 71394

= 163 / 438

= 163

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 163, 438, 440, 853 is 1
