Given numbers are 168, 423, 817, 964

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

Apply this formula for all numbers.

Step1:

LCM(168, 423) = 23688

GCD(168, 423) = ( 168 x 423 ) / 23688

= 168 / 423

= 168

Step2:

LCM(3, 817) = 2451

GCD(3, 817) = ( 3 x 817 ) / 2451

= 3 / 817

= 3

Step3:

LCM(1, 964) = 964

GCD(1, 964) = ( 1 x 964 ) / 964

= 1 / 964

= 1

So, Greatest Common Divisor of 168, 423, 817, 964 is 1
