Given numbers are 496, 390, 638, 149

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

Apply this formula for all numbers.

Step1:

LCM(496, 390) = 96720

GCD(496, 390) = ( 496 x 390 ) / 96720

= 496 / 390

= 496

Step2:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

Step3:

LCM(2, 149) = 298

GCD(2, 149) = ( 2 x 149 ) / 298

= 2 / 149

= 2

So, Greatest Common Divisor of 496, 390, 638, 149 is 1
