Prime factors of 426 are 2 x 3 x 71

Prime factors of 971 are 971

Prime factors of 242 are 2 x 11 x 11

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

Given numbers are 390, 426, 971, 242

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

Apply this formula for all numbers.

Step1:

LCM(390, 426) = 27690

GCD(390, 426) = ( 390 x 426 ) / 27690

= 390 / 426

= 390

Step2:

LCM(6, 971) = 5826

GCD(6, 971) = ( 6 x 971 ) / 5826

= 6 / 971

= 6

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 390, 426, 971, 242 is 1
