Given numbers are 125, 155, 725, 789

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

Apply this formula for all numbers.

Step1:

LCM(125, 155) = 3875

GCD(125, 155) = ( 125 x 155 ) / 3875

= 125 / 155

= 125

Step2:

LCM(5, 725) = 725

GCD(5, 725) = ( 5 x 725 ) / 725

= 5 / 725

= 5

Step3:

LCM(5, 789) = 3945

GCD(5, 789) = ( 5 x 789 ) / 3945

= 5 / 789

= 5

So, Greatest Common Divisor of 125, 155, 725, 789 is 1
