Given numbers are 671, 490, 665, 278

The list of prime factors of all numbers are

Prime factors of 671 are 11 x 61

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 665 are 5 x 7 x 19

Prime factors of 278 are 2 x 139

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

Given numbers are 671, 490, 665, 278

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

Apply this formula for all numbers.

Step1:

LCM(671, 490) = 328790

GCD(671, 490) = ( 671 x 490 ) / 328790

= 671 / 490

= 671

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 671, 490, 665, 278 is 1
