Given numbers are 458, 489, 423, 651
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 489) = 223962
GCD(458, 489) = ( 458 x 489 ) / 223962
= 458 / 489
= 458
Step2:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
Step3:
LCM(1, 651) = 651
GCD(1, 651) = ( 1 x 651 ) / 651
= 1 / 651
= 1
So, Greatest Common Divisor of 458, 489, 423, 651 is 1
