Given numbers are 805, 798, 292, 638

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

Apply this formula for all numbers.

Step1:

LCM(805, 798) = 91770

GCD(805, 798) = ( 805 x 798 ) / 91770

= 805 / 798

= 805

Step2:

LCM(7, 292) = 2044

GCD(7, 292) = ( 7 x 292 ) / 2044

= 7 / 292

= 7

Step3:

LCM(1, 638) = 638

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

= 1 / 638

= 1

So, Greatest Common Divisor of 805, 798, 292, 638 is 1
