Given numbers are 146, 290, 639

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

Apply this formula for all numbers.

Step1:

LCM(146, 290) = 21170

GCD(146, 290) = ( 146 x 290 ) / 21170

= 146 / 290

= 146

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 146, 290, 639 is 1
