Given numbers are 646, 742, 352, 239

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

Apply this formula for all numbers.

Step1:

LCM(646, 742) = 239666

GCD(646, 742) = ( 646 x 742 ) / 239666

= 646 / 742

= 646

Step2:

LCM(2, 352) = 352

GCD(2, 352) = ( 2 x 352 ) / 352

= 2 / 352

= 2

Step3:

LCM(2, 239) = 478

GCD(2, 239) = ( 2 x 239 ) / 478

= 2 / 239

= 2

So, Greatest Common Divisor of 646, 742, 352, 239 is 1
