Given numbers are 645, 998, 562, 814

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

Apply this formula for all numbers.

Step1:

LCM(645, 998) = 643710

GCD(645, 998) = ( 645 x 998 ) / 643710

= 645 / 998

= 645

Step2:

LCM(1, 562) = 562

GCD(1, 562) = ( 1 x 562 ) / 562

= 1 / 562

= 1

Step3:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

So, Greatest Common Divisor of 645, 998, 562, 814 is 1
