Given numbers are 115, 905, 629, 172

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

Apply this formula for all numbers.

Step1:

LCM(115, 905) = 20815

GCD(115, 905) = ( 115 x 905 ) / 20815

= 115 / 905

= 115

Step2:

LCM(5, 629) = 3145

GCD(5, 629) = ( 5 x 629 ) / 3145

= 5 / 629

= 5

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 115, 905, 629, 172 is 1
