GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 306) = 97614
GCD(638, 306) = ( 638 x 306 ) / 97614
= 638 / 306
= 638
Step2:
LCM(2, 967) = 1934
GCD(2, 967) = ( 2 x 967 ) / 1934
= 2 / 967
= 2
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 638, 306, 967, 449 is 1
