Given numbers are 991, 453, 668, 798

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

Apply this formula for all numbers.

Step1:

LCM(991, 453) = 448923

GCD(991, 453) = ( 991 x 453 ) / 448923

= 991 / 453

= 991

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 991, 453, 668, 798 is 1
