Given numbers are 787, 455, 990, 793

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

Apply this formula for all numbers.

Step1:

LCM(787, 455) = 358085

GCD(787, 455) = ( 787 x 455 ) / 358085

= 787 / 455

= 787

Step2:

LCM(1, 990) = 990

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

= 1 / 990

= 1

Step3:

LCM(1, 793) = 793

GCD(1, 793) = ( 1 x 793 ) / 793

= 1 / 793

= 1

So, Greatest Common Divisor of 787, 455, 990, 793 is 1
