Given numbers are 620, 242, 830, 626

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

Apply this formula for all numbers.

Step1:

LCM(620, 242) = 75020

GCD(620, 242) = ( 620 x 242 ) / 75020

= 620 / 242

= 620

Step2:

LCM(2, 830) = 830

GCD(2, 830) = ( 2 x 830 ) / 830

= 2 / 830

= 2

Step3:

LCM(2, 626) = 626

GCD(2, 626) = ( 2 x 626 ) / 626

= 2 / 626

= 2

So, Greatest Common Divisor of 620, 242, 830, 626 is 2
