Given numbers are 819, 689, 830, 168
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 689) = 43407
GCD(819, 689) = ( 819 x 689 ) / 43407
= 819 / 689
= 819
Step2:
LCM(13, 830) = 10790
GCD(13, 830) = ( 13 x 830 ) / 10790
= 13 / 830
= 13
Step3:
LCM(1, 168) = 168
GCD(1, 168) = ( 1 x 168 ) / 168
= 1 / 168
= 1
So, Greatest Common Divisor of 819, 689, 830, 168 is 1
