GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 482) = 91098
GCD(378, 482) = ( 378 x 482 ) / 91098
= 378 / 482
= 378
Step2:
LCM(2, 392) = 392
GCD(2, 392) = ( 2 x 392 ) / 392
= 2 / 392
= 2
Step3:
LCM(2, 663) = 1326
GCD(2, 663) = ( 2 x 663 ) / 1326
= 2 / 663
= 2
So, Greatest Common Divisor of 378, 482, 392, 663 is 1
