GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 638) = 230318
GCD(361, 638) = ( 361 x 638 ) / 230318
= 361 / 638
= 361
Step2:
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
= 1 / 395
= 1
Step3:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
So, Greatest Common Divisor of 361, 638, 395, 397 is 1
