Prime factors of 868 are 2 x 2 x 7 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 100, 397, 454, 868
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(100, 397) = 39700
GCD(100, 397) = ( 100 x 397 ) / 39700
= 100 / 397
= 100
Step2:
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
= 1 / 454
= 1
Step3:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
So, Greatest Common Divisor of 100, 397, 454, 868 is 1
