Given numbers are 744, 945, 278, 155

The list of prime factors of all numbers are

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 278 are 2 x 139

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 744, 945, 278, 155

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

Apply this formula for all numbers.

Step1:

LCM(744, 945) = 234360

GCD(744, 945) = ( 744 x 945 ) / 234360

= 744 / 945

= 744

Step2:

LCM(3, 278) = 834

GCD(3, 278) = ( 3 x 278 ) / 834

= 3 / 278

= 3

Step3:

LCM(1, 155) = 155

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

= 1 / 155

= 1

So, Greatest Common Divisor of 744, 945, 278, 155 is 1
