Given numbers are 724, 406, 863, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(724, 406) = 146972
GCD(724, 406) = ( 724 x 406 ) / 146972
= 724 / 406
= 724
Step2:
LCM(2, 863) = 1726
GCD(2, 863) = ( 2 x 863 ) / 1726
= 2 / 863
= 2
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 724, 406, 863, 815 is 1
