Given numbers are 858, 638, 669, 439

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

Apply this formula for all numbers.

Step1:

LCM(858, 638) = 24882

GCD(858, 638) = ( 858 x 638 ) / 24882

= 858 / 638

= 858

Step2:

LCM(22, 669) = 14718

GCD(22, 669) = ( 22 x 669 ) / 14718

= 22 / 669

= 22

Step3:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

So, Greatest Common Divisor of 858, 638, 669, 439 is 1
