Given numbers are 345, 477, 563, 891

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

Apply this formula for all numbers.

Step1:

LCM(345, 477) = 54855

GCD(345, 477) = ( 345 x 477 ) / 54855

= 345 / 477

= 345

Step2:

LCM(3, 563) = 1689

GCD(3, 563) = ( 3 x 563 ) / 1689

= 3 / 563

= 3

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 345, 477, 563, 891 is 1
