Given numbers are 144, 966, 680, 397

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

Apply this formula for all numbers.

Step1:

LCM(144, 966) = 23184

GCD(144, 966) = ( 144 x 966 ) / 23184

= 144 / 966

= 144

Step2:

LCM(6, 680) = 2040

GCD(6, 680) = ( 6 x 680 ) / 2040

= 6 / 680

= 6

Step3:

LCM(2, 397) = 794

GCD(2, 397) = ( 2 x 397 ) / 794

= 2 / 397

= 2

So, Greatest Common Divisor of 144, 966, 680, 397 is 1
