Given numbers are 655, 731, 966, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 731) = 478805
GCD(655, 731) = ( 655 x 731 ) / 478805
= 655 / 731
= 655
Step2:
LCM(1, 966) = 966
GCD(1, 966) = ( 1 x 966 ) / 966
= 1 / 966
= 1
Step3:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
So, Greatest Common Divisor of 655, 731, 966, 404 is 1
