Given numbers are 403, 390, 565, 923
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 390) = 12090
GCD(403, 390) = ( 403 x 390 ) / 12090
= 403 / 390
= 403
Step2:
LCM(13, 565) = 7345
GCD(13, 565) = ( 13 x 565 ) / 7345
= 13 / 565
= 13
Step3:
LCM(1, 923) = 923
GCD(1, 923) = ( 1 x 923 ) / 923
= 1 / 923
= 1
So, Greatest Common Divisor of 403, 390, 565, 923 is 1
