Given numbers are 667, 621, 981

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

Apply this formula for all numbers.

Step1:

LCM(667, 621) = 18009

GCD(667, 621) = ( 667 x 621 ) / 18009

= 667 / 621

= 667

Step2:

LCM(23, 981) = 22563

GCD(23, 981) = ( 23 x 981 ) / 22563

= 23 / 981

= 23

So, Greatest Common Divisor of 667, 621, 981 is 1
