Given numbers are 260, 639, 507, 655

The list of prime factors of all numbers are

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 639 are 3 x 3 x 71

Prime factors of 507 are 3 x 13 x 13

Prime factors of 655 are 5 x 131

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

Given numbers are 260, 639, 507, 655

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

Apply this formula for all numbers.

Step1:

LCM(260, 639) = 166140

GCD(260, 639) = ( 260 x 639 ) / 166140

= 260 / 639

= 260

Step2:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 260, 639, 507, 655 is 1
