Given numbers are 438, 865, 768, 718

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

Apply this formula for all numbers.

Step1:

LCM(438, 865) = 378870

GCD(438, 865) = ( 438 x 865 ) / 378870

= 438 / 865

= 438

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 718) = 718

GCD(1, 718) = ( 1 x 718 ) / 718

= 1 / 718

= 1

So, Greatest Common Divisor of 438, 865, 768, 718 is 1
