Given numbers are 390, 858, 501, 391
The list of prime factors of all numbers are
Prime factors of 390 are 2 x 3 x 5 x 13
Prime factors of 858 are 2 x 3 x 11 x 13
Prime factors of 501 are 3 x 167
Prime factors of 391 are 17 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 390, 858, 501, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 858) = 4290
GCD(390, 858) = ( 390 x 858 ) / 4290
= 390 / 858
= 390
Step2:
LCM(78, 501) = 13026
GCD(78, 501) = ( 78 x 501 ) / 13026
= 78 / 501
= 78
Step3:
LCM(3, 391) = 1173
GCD(3, 391) = ( 3 x 391 ) / 1173
= 3 / 391
= 3
So, Greatest Common Divisor of 390, 858, 501, 391 is 1
