Given numbers are 819, 726, 409, 747
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 726) = 198198
GCD(819, 726) = ( 819 x 726 ) / 198198
= 819 / 726
= 819
Step2:
LCM(3, 409) = 1227
GCD(3, 409) = ( 3 x 409 ) / 1227
= 3 / 409
= 3
Step3:
LCM(1, 747) = 747
GCD(1, 747) = ( 1 x 747 ) / 747
= 1 / 747
= 1
So, Greatest Common Divisor of 819, 726, 409, 747 is 1
