Given numbers are 620, 488, 442, 149

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

Apply this formula for all numbers.

Step1:

LCM(620, 488) = 75640

GCD(620, 488) = ( 620 x 488 ) / 75640

= 620 / 488

= 620

Step2:

LCM(4, 442) = 884

GCD(4, 442) = ( 4 x 442 ) / 884

= 4 / 442

= 4

Step3:

LCM(2, 149) = 298

GCD(2, 149) = ( 2 x 149 ) / 298

= 2 / 149

= 2

So, Greatest Common Divisor of 620, 488, 442, 149 is 1
