Given numbers are 153, 825, 12, 491

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

Apply this formula for all numbers.

Step1:

LCM(153, 825) = 42075

GCD(153, 825) = ( 153 x 825 ) / 42075

= 153 / 825

= 153

Step2:

LCM(3, 12) = 12

GCD(3, 12) = ( 3 x 12 ) / 12

= 3 / 12

= 3

Step3:

LCM(3, 491) = 1473

GCD(3, 491) = ( 3 x 491 ) / 1473

= 3 / 491

= 3

So, Greatest Common Divisor of 153, 825, 12, 491 is 1
