Given numbers are 520, 445, 685, 880

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

Apply this formula for all numbers.

Step1:

LCM(520, 445) = 46280

GCD(520, 445) = ( 520 x 445 ) / 46280

= 520 / 445

= 520

Step2:

LCM(5, 685) = 685

GCD(5, 685) = ( 5 x 685 ) / 685

= 5 / 685

= 5

Step3:

LCM(5, 880) = 880

GCD(5, 880) = ( 5 x 880 ) / 880

= 5 / 880

= 5

So, Greatest Common Divisor of 520, 445, 685, 880 is 5
