Given numbers are 520, 430, 670, 845

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

Apply this formula for all numbers.

Step1:

LCM(520, 430) = 22360

GCD(520, 430) = ( 520 x 430 ) / 22360

= 520 / 430

= 520

Step2:

LCM(10, 670) = 670

GCD(10, 670) = ( 10 x 670 ) / 670

= 10 / 670

= 10

Step3:

LCM(10, 845) = 1690

GCD(10, 845) = ( 10 x 845 ) / 1690

= 10 / 845

= 10

So, Greatest Common Divisor of 520, 430, 670, 845 is 5
