The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 111, 630, 450, 397
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(111, 630) = 23310
GCD(111, 630) = ( 111 x 630 ) / 23310
= 111 / 630
= 111
Step2:
LCM(3, 450) = 450
GCD(3, 450) = ( 3 x 450 ) / 450
= 3 / 450
= 3
Step3:
LCM(3, 397) = 1191
GCD(3, 397) = ( 3 x 397 ) / 1191
= 3 / 397
= 3
So, Greatest Common Divisor of 111, 630, 450, 397 is 1
