Given numbers are 638, 573, 579, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 573) = 365574
GCD(638, 573) = ( 638 x 573 ) / 365574
= 638 / 573
= 638
Step2:
LCM(1, 579) = 579
GCD(1, 579) = ( 1 x 579 ) / 579
= 1 / 579
= 1
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 638, 573, 579, 393 is 1
