Given numbers are 680, 245, 787, 181

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 245 are 5 x 7 x 7

Prime factors of 787 are 787

Prime factors of 181 are 181

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

Given numbers are 680, 245, 787, 181

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

Apply this formula for all numbers.

Step1:

LCM(680, 245) = 33320

GCD(680, 245) = ( 680 x 245 ) / 33320

= 680 / 245

= 680

Step2:

LCM(5, 787) = 3935

GCD(5, 787) = ( 5 x 787 ) / 3935

= 5 / 787

= 5

Step3:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

So, Greatest Common Divisor of 680, 245, 787, 181 is 1
