Given numbers are 398, 911, 987, 177

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

Apply this formula for all numbers.

Step1:

LCM(398, 911) = 362578

GCD(398, 911) = ( 398 x 911 ) / 362578

= 398 / 911

= 398

Step2:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

Step3:

LCM(1, 177) = 177

GCD(1, 177) = ( 1 x 177 ) / 177

= 1 / 177

= 1

So, Greatest Common Divisor of 398, 911, 987, 177 is 1
