Given numbers are 723, 320, 638, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(723, 320) = 231360
GCD(723, 320) = ( 723 x 320 ) / 231360
= 723 / 320
= 723
Step2:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 723, 320, 638, 663 is 1
