Given numbers are 520, 425, 172

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

Apply this formula for all numbers.

Step1:

LCM(520, 425) = 44200

GCD(520, 425) = ( 520 x 425 ) / 44200

= 520 / 425

= 520

Step2:

LCM(5, 172) = 860

GCD(5, 172) = ( 5 x 172 ) / 860

= 5 / 172

= 5

So, Greatest Common Divisor of 520, 425, 172 is 1
