Given numbers are 300, 387, 649, 865
The list of prime factors of all numbers are
Prime factors of 300 are 2 x 2 x 3 x 5 x 5
Prime factors of 387 are 3 x 3 x 43
Prime factors of 649 are 11 x 59
Prime factors of 865 are 5 x 173
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 300, 387, 649, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(300, 387) = 38700
GCD(300, 387) = ( 300 x 387 ) / 38700
= 300 / 387
= 300
Step2:
LCM(3, 649) = 1947
GCD(3, 649) = ( 3 x 649 ) / 1947
= 3 / 649
= 3
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 300, 387, 649, 865 is 1
