GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 831) = 104706
GCD(378, 831) = ( 378 x 831 ) / 104706
= 378 / 831
= 378
Step2:
LCM(3, 843) = 843
GCD(3, 843) = ( 3 x 843 ) / 843
= 3 / 843
= 3
Step3:
LCM(3, 128) = 384
GCD(3, 128) = ( 3 x 128 ) / 384
= 3 / 128
= 3
So, Greatest Common Divisor of 378, 831, 843, 128 is 1
