Given numbers are 403, 280, 976, 654

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 976 are 2 x 2 x 2 x 2 x 61

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 403, 280, 976, 654

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

Apply this formula for all numbers.

Step1:

LCM(403, 280) = 112840

GCD(403, 280) = ( 403 x 280 ) / 112840

= 403 / 280

= 403

Step2:

LCM(1, 976) = 976

GCD(1, 976) = ( 1 x 976 ) / 976

= 1 / 976

= 1

Step3:

LCM(1, 654) = 654

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

= 1 / 654

= 1

So, Greatest Common Divisor of 403, 280, 976, 654 is 1
