Given numbers are 705, 393, 738, 403
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 393) = 92355
GCD(705, 393) = ( 705 x 393 ) / 92355
= 705 / 393
= 705
Step2:
LCM(3, 738) = 738
GCD(3, 738) = ( 3 x 738 ) / 738
= 3 / 738
= 3
Step3:
LCM(3, 403) = 1209
GCD(3, 403) = ( 3 x 403 ) / 1209
= 3 / 403
= 3
So, Greatest Common Divisor of 705, 393, 738, 403 is 1
