Given numbers are 406, 493, 620, 772

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

Apply this formula for all numbers.

Step1:

LCM(406, 493) = 6902

GCD(406, 493) = ( 406 x 493 ) / 6902

= 406 / 493

= 406

Step2:

LCM(29, 620) = 17980

GCD(29, 620) = ( 29 x 620 ) / 17980

= 29 / 620

= 29

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 406, 493, 620, 772 is 1
