Given numbers are 842, 664, 400

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

Apply this formula for all numbers.

Step1:

LCM(842, 664) = 279544

GCD(842, 664) = ( 842 x 664 ) / 279544

= 842 / 664

= 842

Step2:

LCM(2, 400) = 400

GCD(2, 400) = ( 2 x 400 ) / 400

= 2 / 400

= 2

So, Greatest Common Divisor of 842, 664, 400 is 2
