Given numbers are 409, 865, 155, 590

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

Apply this formula for all numbers.

Step1:

LCM(409, 865) = 353785

GCD(409, 865) = ( 409 x 865 ) / 353785

= 409 / 865

= 409

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 590) = 590

GCD(1, 590) = ( 1 x 590 ) / 590

= 1 / 590

= 1

So, Greatest Common Divisor of 409, 865, 155, 590 is 1
