Given numbers are 416, 210, 654, 257

The list of prime factors of all numbers are

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 654 are 2 x 3 x 109

Prime factors of 257 are 257

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

Given numbers are 416, 210, 654, 257

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

Apply this formula for all numbers.

Step1:

LCM(416, 210) = 43680

GCD(416, 210) = ( 416 x 210 ) / 43680

= 416 / 210

= 416

Step2:

LCM(2, 654) = 654

GCD(2, 654) = ( 2 x 654 ) / 654

= 2 / 654

= 2

Step3:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

So, Greatest Common Divisor of 416, 210, 654, 257 is 1
