GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(223, 487) = 108601
GCD(223, 487) = ( 223 x 487 ) / 108601
= 223 / 487
= 223
Step2:
LCM(1, 319) = 319
GCD(1, 319) = ( 1 x 319 ) / 319
= 1 / 319
= 1
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 223, 487, 319, 720 is 1
