GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 819) = 391482
GCD(478, 819) = ( 478 x 819 ) / 391482
= 478 / 819
= 478
Step2:
LCM(1, 586) = 586
GCD(1, 586) = ( 1 x 586 ) / 586
= 1 / 586
= 1
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 478, 819, 586, 978 is 1
