GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 212) = 22684
GCD(428, 212) = ( 428 x 212 ) / 22684
= 428 / 212
= 428
Step2:
LCM(4, 138) = 276
GCD(4, 138) = ( 4 x 138 ) / 276
= 4 / 138
= 4
Step3:
LCM(2, 384) = 384
GCD(2, 384) = ( 2 x 384 ) / 384
= 2 / 384
= 2
So, Greatest Common Divisor of 428, 212, 138, 384 is 2
