Given numbers are 628, 664, 358, 845

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

Apply this formula for all numbers.

Step1:

LCM(628, 664) = 104248

GCD(628, 664) = ( 628 x 664 ) / 104248

= 628 / 664

= 628

Step2:

LCM(4, 358) = 716

GCD(4, 358) = ( 4 x 358 ) / 716

= 4 / 358

= 4

Step3:

LCM(2, 845) = 1690

GCD(2, 845) = ( 2 x 845 ) / 1690

= 2 / 845

= 2

So, Greatest Common Divisor of 628, 664, 358, 845 is 1
