Given numbers are 640, 278, 901, 506

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 278 are 2 x 139

Prime factors of 901 are 17 x 53

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 640, 278, 901, 506

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

Apply this formula for all numbers.

Step1:

LCM(640, 278) = 88960

GCD(640, 278) = ( 640 x 278 ) / 88960

= 640 / 278

= 640

Step2:

LCM(2, 901) = 1802

GCD(2, 901) = ( 2 x 901 ) / 1802

= 2 / 901

= 2

Step3:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

So, Greatest Common Divisor of 640, 278, 901, 506 is 1
