Given numbers are 742, 905, 978, 679
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 905) = 671510
GCD(742, 905) = ( 742 x 905 ) / 671510
= 742 / 905
= 742
Step2:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
Step3:
LCM(1, 679) = 679
GCD(1, 679) = ( 1 x 679 ) / 679
= 1 / 679
= 1
So, Greatest Common Divisor of 742, 905, 978, 679 is 1
