Given numbers are 480, 245, 931, 654

The list of prime factors of all numbers are

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 245 are 5 x 7 x 7

Prime factors of 931 are 7 x 7 x 19

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 480, 245, 931, 654

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

Apply this formula for all numbers.

Step1:

LCM(480, 245) = 23520

GCD(480, 245) = ( 480 x 245 ) / 23520

= 480 / 245

= 480

Step2:

LCM(5, 931) = 4655

GCD(5, 931) = ( 5 x 931 ) / 4655

= 5 / 931

= 5

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 480, 245, 931, 654 is 1
