Given numbers are 734, 640, 345, 155

The list of prime factors of all numbers are

Prime factors of 734 are 2 x 367

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

Prime factors of 345 are 3 x 5 x 23

Prime factors of 155 are 5 x 31

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

Given numbers are 734, 640, 345, 155

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

Apply this formula for all numbers.

Step1:

LCM(734, 640) = 234880

GCD(734, 640) = ( 734 x 640 ) / 234880

= 734 / 640

= 734

Step2:

LCM(2, 345) = 690

GCD(2, 345) = ( 2 x 345 ) / 690

= 2 / 345

= 2

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 734, 640, 345, 155 is 1
