Given numbers are 393, 660, 568, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 660) = 86460
GCD(393, 660) = ( 393 x 660 ) / 86460
= 393 / 660
= 393
Step2:
LCM(3, 568) = 1704
GCD(3, 568) = ( 3 x 568 ) / 1704
= 3 / 568
= 3
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 393, 660, 568, 457 is 1
