Given numbers are 499, 220, 170, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(499, 220) = 109780
GCD(499, 220) = ( 499 x 220 ) / 109780
= 499 / 220
= 499
Step2:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 499, 220, 170, 689 is 1
