GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 432) = 70416
GCD(978, 432) = ( 978 x 432 ) / 70416
= 978 / 432
= 978
Step2:
LCM(6, 403) = 2418
GCD(6, 403) = ( 6 x 403 ) / 2418
= 6 / 403
= 6
Step3:
LCM(1, 839) = 839
GCD(1, 839) = ( 1 x 839 ) / 839
= 1 / 839
= 1
So, Greatest Common Divisor of 978, 432, 403, 839 is 1
