Given numbers are 780, 266, 523, 245

The list of prime factors of all numbers are

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

Prime factors of 266 are 2 x 7 x 19

Prime factors of 523 are 523

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 780, 266, 523, 245

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

Apply this formula for all numbers.

Step1:

LCM(780, 266) = 103740

GCD(780, 266) = ( 780 x 266 ) / 103740

= 780 / 266

= 780

Step2:

LCM(2, 523) = 1046

GCD(2, 523) = ( 2 x 523 ) / 1046

= 2 / 523

= 2

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 780, 266, 523, 245 is 1
