Given numbers are 361, 531, 639

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

Apply this formula for all numbers.

Step1:

LCM(361, 531) = 191691

GCD(361, 531) = ( 361 x 531 ) / 191691

= 361 / 531

= 361

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 361, 531, 639 is 1
