GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(459, 391) = 10557
GCD(459, 391) = ( 459 x 391 ) / 10557
= 459 / 391
= 459
Step2:
LCM(17, 447) = 7599
GCD(17, 447) = ( 17 x 447 ) / 7599
= 17 / 447
= 17
Step3:
LCM(1, 971) = 971
GCD(1, 971) = ( 1 x 971 ) / 971
= 1 / 971
= 1
So, Greatest Common Divisor of 459, 391, 447, 971 is 1
