Given numbers are 668, 172, 123, 397

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

Apply this formula for all numbers.

Step1:

LCM(668, 172) = 28724

GCD(668, 172) = ( 668 x 172 ) / 28724

= 668 / 172

= 668

Step2:

LCM(4, 123) = 492

GCD(4, 123) = ( 4 x 123 ) / 492

= 4 / 123

= 4

Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 668, 172, 123, 397 is 1
