Given numbers are 603, 198, 989, 917

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

Apply this formula for all numbers.

Step1:

LCM(603, 198) = 13266

GCD(603, 198) = ( 603 x 198 ) / 13266

= 603 / 198

= 603

Step2:

LCM(9, 989) = 8901

GCD(9, 989) = ( 9 x 989 ) / 8901

= 9 / 989

= 9

Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

So, Greatest Common Divisor of 603, 198, 989, 917 is 1
