Given numbers are 438, 770, 859, 665

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

Apply this formula for all numbers.

Step1:

LCM(438, 770) = 168630

GCD(438, 770) = ( 438 x 770 ) / 168630

= 438 / 770

= 438

Step2:

LCM(2, 859) = 1718

GCD(2, 859) = ( 2 x 859 ) / 1718

= 2 / 859

= 2

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 438, 770, 859, 665 is 1
