Given numbers are 231, 658, 489, 185
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 658) = 21714
GCD(231, 658) = ( 231 x 658 ) / 21714
= 231 / 658
= 231
Step2:
LCM(7, 489) = 3423
GCD(7, 489) = ( 7 x 489 ) / 3423
= 7 / 489
= 7
Step3:
LCM(1, 185) = 185
GCD(1, 185) = ( 1 x 185 ) / 185
= 1 / 185
= 1
So, Greatest Common Divisor of 231, 658, 489, 185 is 1
