Given numbers are 681, 357, 658, 998

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

Apply this formula for all numbers.

Step1:

LCM(681, 357) = 81039

GCD(681, 357) = ( 681 x 357 ) / 81039

= 681 / 357

= 681

Step2:

LCM(3, 658) = 1974

GCD(3, 658) = ( 3 x 658 ) / 1974

= 3 / 658

= 3

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 681, 357, 658, 998 is 1
