Given numbers are 655, 520, 257, 218

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 257 are 257

Prime factors of 218 are 2 x 109

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

Given numbers are 655, 520, 257, 218

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

Apply this formula for all numbers.

Step1:

LCM(655, 520) = 68120

GCD(655, 520) = ( 655 x 520 ) / 68120

= 655 / 520

= 655

Step2:

LCM(5, 257) = 1285

GCD(5, 257) = ( 5 x 257 ) / 1285

= 5 / 257

= 5

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 655, 520, 257, 218 is 1
