Given numbers are 755, 432, 286, 138

The list of prime factors of all numbers are

Prime factors of 755 are 5 x 151

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 286 are 2 x 11 x 13

Prime factors of 138 are 2 x 3 x 23

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

Given numbers are 755, 432, 286, 138

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

Apply this formula for all numbers.

Step1:

LCM(755, 432) = 326160

GCD(755, 432) = ( 755 x 432 ) / 326160

= 755 / 432

= 755

Step2:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 755, 432, 286, 138 is 1
