Given numbers are 403, 713, 338, 668

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

Apply this formula for all numbers.

Step1:

LCM(403, 713) = 9269

GCD(403, 713) = ( 403 x 713 ) / 9269

= 403 / 713

= 403

Step2:

LCM(31, 338) = 10478

GCD(31, 338) = ( 31 x 338 ) / 10478

= 31 / 338

= 31

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 403, 713, 338, 668 is 1
