Given numbers are 438, 784, 154, 866

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

Apply this formula for all numbers.

Step1:

LCM(438, 784) = 171696

GCD(438, 784) = ( 438 x 784 ) / 171696

= 438 / 784

= 438

Step2:

LCM(2, 154) = 154

GCD(2, 154) = ( 2 x 154 ) / 154

= 2 / 154

= 2

Step3:

LCM(2, 866) = 866

GCD(2, 866) = ( 2 x 866 ) / 866

= 2 / 866

= 2

So, Greatest Common Divisor of 438, 784, 154, 866 is 2
