Given numbers are 688, 817, 173, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 817) = 13072
GCD(688, 817) = ( 688 x 817 ) / 13072
= 688 / 817
= 688
Step2:
LCM(43, 173) = 7439
GCD(43, 173) = ( 43 x 173 ) / 7439
= 43 / 173
= 43
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 688, 817, 173, 489 is 1
