Given numbers are 998, 653, 419, 858

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

Apply this formula for all numbers.

Step1:

LCM(998, 653) = 651694

GCD(998, 653) = ( 998 x 653 ) / 651694

= 998 / 653

= 998

Step2:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 998, 653, 419, 858 is 1
