Given numbers are 398, 860, 880, 998

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

Apply this formula for all numbers.

Step1:

LCM(398, 860) = 171140

GCD(398, 860) = ( 398 x 860 ) / 171140

= 398 / 860

= 398

Step2:

LCM(2, 880) = 880

GCD(2, 880) = ( 2 x 880 ) / 880

= 2 / 880

= 2

Step3:

LCM(2, 998) = 998

GCD(2, 998) = ( 2 x 998 ) / 998

= 2 / 998

= 2

So, Greatest Common Divisor of 398, 860, 880, 998 is 2
