Given numbers are 399, 861, 919, 900

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

Apply this formula for all numbers.

Step1:

LCM(399, 861) = 16359

GCD(399, 861) = ( 399 x 861 ) / 16359

= 399 / 861

= 399

Step2:

LCM(21, 919) = 19299

GCD(21, 919) = ( 21 x 919 ) / 19299

= 21 / 919

= 21

Step3:

LCM(1, 900) = 900

GCD(1, 900) = ( 1 x 900 ) / 900

= 1 / 900

= 1

So, Greatest Common Divisor of 399, 861, 919, 900 is 1
