Given numbers are 764, 798, 27, 990

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

Apply this formula for all numbers.

Step1:

LCM(764, 798) = 304836

GCD(764, 798) = ( 764 x 798 ) / 304836

= 764 / 798

= 764

Step2:

LCM(2, 27) = 54

GCD(2, 27) = ( 2 x 27 ) / 54

= 2 / 27

= 2

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 764, 798, 27, 990 is 1
