Given numbers are 991, 889, 649, 710

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

Apply this formula for all numbers.

Step1:

LCM(991, 889) = 880999

GCD(991, 889) = ( 991 x 889 ) / 880999

= 991 / 889

= 991

Step2:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

Step3:

LCM(1, 710) = 710

GCD(1, 710) = ( 1 x 710 ) / 710

= 1 / 710

= 1

So, Greatest Common Divisor of 991, 889, 649, 710 is 1
