Given numbers are 646, 757, 458, 280

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 757 are 757

Prime factors of 458 are 2 x 229

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 646, 757, 458, 280

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

Apply this formula for all numbers.

Step1:

LCM(646, 757) = 489022

GCD(646, 757) = ( 646 x 757 ) / 489022

= 646 / 757

= 646

Step2:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

Step3:

LCM(1, 280) = 280

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

= 1 / 280

= 1

So, Greatest Common Divisor of 646, 757, 458, 280 is 1
