Given numbers are 438, 415, 262, 128

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 415 are 5 x 83

Prime factors of 262 are 2 x 131

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 438, 415, 262, 128

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

Apply this formula for all numbers.

Step1:

LCM(438, 415) = 181770

GCD(438, 415) = ( 438 x 415 ) / 181770

= 438 / 415

= 438

Step2:

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

= 1 / 262

= 1

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 438, 415, 262, 128 is 1
