Given numbers are 998, 618, 643, 913

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

Apply this formula for all numbers.

Step1:

LCM(998, 618) = 308382

GCD(998, 618) = ( 998 x 618 ) / 308382

= 998 / 618

= 998

Step2:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

Step3:

LCM(1, 913) = 913

GCD(1, 913) = ( 1 x 913 ) / 913

= 1 / 913

= 1

So, Greatest Common Divisor of 998, 618, 643, 913 is 1
