Given numbers are 611, 260, 649, 905

The list of prime factors of all numbers are

Prime factors of 611 are 13 x 47

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

Prime factors of 649 are 11 x 59

Prime factors of 905 are 5 x 181

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

Given numbers are 611, 260, 649, 905

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

Apply this formula for all numbers.

Step1:

LCM(611, 260) = 12220

GCD(611, 260) = ( 611 x 260 ) / 12220

= 611 / 260

= 611

Step2:

LCM(13, 649) = 8437

GCD(13, 649) = ( 13 x 649 ) / 8437

= 13 / 649

= 13

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 611, 260, 649, 905 is 1
