Given numbers are 620, 830, 450, 488

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

Apply this formula for all numbers.

Step1:

LCM(620, 830) = 51460

GCD(620, 830) = ( 620 x 830 ) / 51460

= 620 / 830

= 620

Step2:

LCM(10, 450) = 450

GCD(10, 450) = ( 10 x 450 ) / 450

= 10 / 450

= 10

Step3:

LCM(10, 488) = 2440

GCD(10, 488) = ( 10 x 488 ) / 2440

= 10 / 488

= 10

So, Greatest Common Divisor of 620, 830, 450, 488 is 2
