Given numbers are 388, 330, 139, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 330) = 64020
GCD(388, 330) = ( 388 x 330 ) / 64020
= 388 / 330
= 388
Step2:
LCM(2, 139) = 278
GCD(2, 139) = ( 2 x 139 ) / 278
= 2 / 139
= 2
Step3:
LCM(1, 321) = 321
GCD(1, 321) = ( 1 x 321 ) / 321
= 1 / 321
= 1
So, Greatest Common Divisor of 388, 330, 139, 321 is 1
