Given numbers are 786, 278, 494, 245

The list of prime factors of all numbers are

Prime factors of 786 are 2 x 3 x 131

Prime factors of 278 are 2 x 139

Prime factors of 494 are 2 x 13 x 19

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 786, 278, 494, 245

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

Apply this formula for all numbers.

Step1:

LCM(786, 278) = 109254

GCD(786, 278) = ( 786 x 278 ) / 109254

= 786 / 278

= 786

Step2:

LCM(2, 494) = 494

GCD(2, 494) = ( 2 x 494 ) / 494

= 2 / 494

= 2

Step3:

LCM(2, 245) = 490

GCD(2, 245) = ( 2 x 245 ) / 490

= 2 / 245

= 2

So, Greatest Common Divisor of 786, 278, 494, 245 is 1
