Given numbers are 253, 330, 782, 280

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 782 are 2 x 17 x 23

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

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

Given numbers are 253, 330, 782, 280

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

Apply this formula for all numbers.

Step1:

LCM(253, 330) = 7590

GCD(253, 330) = ( 253 x 330 ) / 7590

= 253 / 330

= 253

Step2:

LCM(11, 782) = 8602

GCD(11, 782) = ( 11 x 782 ) / 8602

= 11 / 782

= 11

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 253, 330, 782, 280 is 1
