Given numbers are 221, 976, 12, 912

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

Apply this formula for all numbers.

Step1:

LCM(221, 976) = 215696

GCD(221, 976) = ( 221 x 976 ) / 215696

= 221 / 976

= 221

Step2:

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

= 1 / 12

= 1

Step3:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

So, Greatest Common Divisor of 221, 976, 12, 912 is 1
