Given numbers are 393, 453, 239, 456
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 453) = 59343
GCD(393, 453) = ( 393 x 453 ) / 59343
= 393 / 453
= 393
Step2:
LCM(3, 239) = 717
GCD(3, 239) = ( 3 x 239 ) / 717
= 3 / 239
= 3
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 393, 453, 239, 456 is 1
