GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(724, 921) = 666804
GCD(724, 921) = ( 724 x 921 ) / 666804
= 724 / 921
= 724
Step2:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 724, 921, 605, 978 is 1
