Given numbers are 245, 462, 390, 532

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 462 are 2 x 3 x 7 x 11

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

Prime factors of 532 are 2 x 2 x 7 x 19

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

Given numbers are 245, 462, 390, 532

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

Apply this formula for all numbers.

Step1:

LCM(245, 462) = 16170

GCD(245, 462) = ( 245 x 462 ) / 16170

= 245 / 462

= 245

Step2:

LCM(7, 390) = 2730

GCD(7, 390) = ( 7 x 390 ) / 2730

= 7 / 390

= 7

Step3:

LCM(1, 532) = 532

GCD(1, 532) = ( 1 x 532 ) / 532

= 1 / 532

= 1

So, Greatest Common Divisor of 245, 462, 390, 532 is 1
