Given numbers are 515, 189, 155, 425

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

Apply this formula for all numbers.

Step1:

LCM(515, 189) = 97335

GCD(515, 189) = ( 515 x 189 ) / 97335

= 515 / 189

= 515

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 515, 189, 155, 425 is 1
