Given numbers are 638, 218, 833, 202

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

Apply this formula for all numbers.

Step1:

LCM(638, 218) = 69542

GCD(638, 218) = ( 638 x 218 ) / 69542

= 638 / 218

= 638

Step2:

LCM(2, 833) = 1666

GCD(2, 833) = ( 2 x 833 ) / 1666

= 2 / 833

= 2

Step3:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

So, Greatest Common Divisor of 638, 218, 833, 202 is 1
