Given numbers are 342, 639, 194, 513

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

Apply this formula for all numbers.

Step1:

LCM(342, 639) = 24282

GCD(342, 639) = ( 342 x 639 ) / 24282

= 342 / 639

= 342

Step2:

LCM(9, 194) = 1746

GCD(9, 194) = ( 9 x 194 ) / 1746

= 9 / 194

= 9

Step3:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

So, Greatest Common Divisor of 342, 639, 194, 513 is 1
