Given numbers are 620, 405, 328, 919

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

Apply this formula for all numbers.

Step1:

LCM(620, 405) = 50220

GCD(620, 405) = ( 620 x 405 ) / 50220

= 620 / 405

= 620

Step2:

LCM(5, 328) = 1640

GCD(5, 328) = ( 5 x 328 ) / 1640

= 5 / 328

= 5

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 620, 405, 328, 919 is 1
