Given numbers are 889, 665, 986, 721

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

Apply this formula for all numbers.

Step1:

LCM(889, 665) = 84455

GCD(889, 665) = ( 889 x 665 ) / 84455

= 889 / 665

= 889

Step2:

LCM(7, 986) = 6902

GCD(7, 986) = ( 7 x 986 ) / 6902

= 7 / 986

= 7

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 889, 665, 986, 721 is 1
