Given numbers are 620, 480, 130, 208

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

Apply this formula for all numbers.

Step1:

LCM(620, 480) = 14880

GCD(620, 480) = ( 620 x 480 ) / 14880

= 620 / 480

= 620

Step2:

LCM(20, 130) = 260

GCD(20, 130) = ( 20 x 130 ) / 260

= 20 / 130

= 20

Step3:

LCM(10, 208) = 1040

GCD(10, 208) = ( 10 x 208 ) / 1040

= 10 / 208

= 10

So, Greatest Common Divisor of 620, 480, 130, 208 is 2
