Given numbers are 520, 620, 818, 448

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

Apply this formula for all numbers.

Step1:

LCM(520, 620) = 16120

GCD(520, 620) = ( 520 x 620 ) / 16120

= 520 / 620

= 520

Step2:

LCM(20, 818) = 8180

GCD(20, 818) = ( 20 x 818 ) / 8180

= 20 / 818

= 20

Step3:

LCM(2, 448) = 448

GCD(2, 448) = ( 2 x 448 ) / 448

= 2 / 448

= 2

So, Greatest Common Divisor of 520, 620, 818, 448 is 2
