Given numbers are 720, 621, 793
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 621) = 49680
GCD(720, 621) = ( 720 x 621 ) / 49680
= 720 / 621
= 720
Step2:
LCM(9, 793) = 7137
GCD(9, 793) = ( 9 x 793 ) / 7137
= 9 / 793
= 9
So, Greatest Common Divisor of 720, 621, 793 is 1
