Given numbers are 398, 859, 80, 955

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

Apply this formula for all numbers.

Step1:

LCM(398, 859) = 341882

GCD(398, 859) = ( 398 x 859 ) / 341882

= 398 / 859

= 398

Step2:

LCM(1, 80) = 80

GCD(1, 80) = ( 1 x 80 ) / 80

= 1 / 80

= 1

Step3:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

So, Greatest Common Divisor of 398, 859, 80, 955 is 1
