Given numbers are 393, 555, 581, 766
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 555) = 72705
GCD(393, 555) = ( 393 x 555 ) / 72705
= 393 / 555
= 393
Step2:
LCM(3, 581) = 1743
GCD(3, 581) = ( 3 x 581 ) / 1743
= 3 / 581
= 3
Step3:
LCM(1, 766) = 766
GCD(1, 766) = ( 1 x 766 ) / 766
= 1 / 766
= 1
So, Greatest Common Divisor of 393, 555, 581, 766 is 1
