Steps to Calculate GCD of 151, 159, 489, 689 using LCM Formula
Given numbers are 151, 159, 489, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(151, 159) = 24009
GCD(151, 159) = ( 151 x 159 ) / 24009
= 151 / 159
= 151
Step2:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 151, 159, 489, 689 is 1
