Given numbers are 279, 825, 749, 170

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

Apply this formula for all numbers.

Step1:

LCM(279, 825) = 76725

GCD(279, 825) = ( 279 x 825 ) / 76725

= 279 / 825

= 279

Step2:

LCM(3, 749) = 2247

GCD(3, 749) = ( 3 x 749 ) / 2247

= 3 / 749

= 3

Step3:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 279, 825, 749, 170 is 1
