Given numbers are 664, 138, 846, 403

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

Apply this formula for all numbers.

Step1:

LCM(664, 138) = 45816

GCD(664, 138) = ( 664 x 138 ) / 45816

= 664 / 138

= 664

Step2:

LCM(2, 846) = 846

GCD(2, 846) = ( 2 x 846 ) / 846

= 2 / 846

= 2

Step3:

LCM(2, 403) = 806

GCD(2, 403) = ( 2 x 403 ) / 806

= 2 / 403

= 2

So, Greatest Common Divisor of 664, 138, 846, 403 is 1
