Given numbers are 758, 345, 546, 640

The list of prime factors of all numbers are

Prime factors of 758 are 2 x 379

Prime factors of 345 are 3 x 5 x 23

Prime factors of 546 are 2 x 3 x 7 x 13

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

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

Given numbers are 758, 345, 546, 640

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

Apply this formula for all numbers.

Step1:

LCM(758, 345) = 261510

GCD(758, 345) = ( 758 x 345 ) / 261510

= 758 / 345

= 758

Step2:

LCM(1, 546) = 546

GCD(1, 546) = ( 1 x 546 ) / 546

= 1 / 546

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 758, 345, 546, 640 is 1
