Given numbers are 238, 129, 15, 825

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

Apply this formula for all numbers.

Step1:

LCM(238, 129) = 30702

GCD(238, 129) = ( 238 x 129 ) / 30702

= 238 / 129

= 238

Step2:

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

= 1 / 15

= 1

Step3:

LCM(1, 825) = 825

GCD(1, 825) = ( 1 x 825 ) / 825

= 1 / 825

= 1

So, Greatest Common Divisor of 238, 129, 15, 825 is 1
