Given numbers are 345, 915, 891, 877

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

Apply this formula for all numbers.

Step1:

LCM(345, 915) = 21045

GCD(345, 915) = ( 345 x 915 ) / 21045

= 345 / 915

= 345

Step2:

LCM(15, 891) = 4455

GCD(15, 891) = ( 15 x 891 ) / 4455

= 15 / 891

= 15

Step3:

LCM(3, 877) = 2631

GCD(3, 877) = ( 3 x 877 ) / 2631

= 3 / 877

= 3

So, Greatest Common Divisor of 345, 915, 891, 877 is 1
