Given numbers are 190, 345, 130, 620

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

Apply this formula for all numbers.

Step1:

LCM(190, 345) = 13110

GCD(190, 345) = ( 190 x 345 ) / 13110

= 190 / 345

= 190

Step2:

LCM(5, 130) = 130

GCD(5, 130) = ( 5 x 130 ) / 130

= 5 / 130

= 5

Step3:

LCM(5, 620) = 620

GCD(5, 620) = ( 5 x 620 ) / 620

= 5 / 620

= 5

So, Greatest Common Divisor of 190, 345, 130, 620 is 5
