Given numbers are 245, 780, 614, 687

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 614 are 2 x 307

Prime factors of 687 are 3 x 229

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

Given numbers are 245, 780, 614, 687

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

Apply this formula for all numbers.

Step1:

LCM(245, 780) = 38220

GCD(245, 780) = ( 245 x 780 ) / 38220

= 245 / 780

= 245

Step2:

LCM(5, 614) = 3070

GCD(5, 614) = ( 5 x 614 ) / 3070

= 5 / 614

= 5

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 245, 780, 614, 687 is 1
