Given numbers are 161, 835, 638, 494

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

Apply this formula for all numbers.

Step1:

LCM(161, 835) = 134435

GCD(161, 835) = ( 161 x 835 ) / 134435

= 161 / 835

= 161

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 494) = 494

GCD(1, 494) = ( 1 x 494 ) / 494

= 1 / 494

= 1

So, Greatest Common Divisor of 161, 835, 638, 494 is 1
