Given numbers are 345, 245, 278, 374

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 245 are 5 x 7 x 7

Prime factors of 278 are 2 x 139

Prime factors of 374 are 2 x 11 x 17

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

Given numbers are 345, 245, 278, 374

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

Apply this formula for all numbers.

Step1:

LCM(345, 245) = 16905

GCD(345, 245) = ( 345 x 245 ) / 16905

= 345 / 245

= 345

Step2:

LCM(5, 278) = 1390

GCD(5, 278) = ( 5 x 278 ) / 1390

= 5 / 278

= 5

Step3:

LCM(1, 374) = 374

GCD(1, 374) = ( 1 x 374 ) / 374

= 1 / 374

= 1

So, Greatest Common Divisor of 345, 245, 278, 374 is 1
