Given numbers are 390, 958, 611, 644

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 958 are 2 x 479

Prime factors of 611 are 13 x 47

Prime factors of 644 are 2 x 2 x 7 x 23

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 390, 958, 611, 644

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(390, 958) = 186810

GCD(390, 958) = ( 390 x 958 ) / 186810

= 390 / 958

= 390

Step2:

LCM(2, 611) = 1222

GCD(2, 611) = ( 2 x 611 ) / 1222

= 2 / 611

= 2

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 390, 958, 611, 644 is 1
