Given numbers are 345, 978, 891, 674

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

Apply this formula for all numbers.

Step1:

LCM(345, 978) = 112470

GCD(345, 978) = ( 345 x 978 ) / 112470

= 345 / 978

= 345

Step2:

LCM(3, 891) = 891

GCD(3, 891) = ( 3 x 891 ) / 891

= 3 / 891

= 3

Step3:

LCM(3, 674) = 2022

GCD(3, 674) = ( 3 x 674 ) / 2022

= 3 / 674

= 3

So, Greatest Common Divisor of 345, 978, 891, 674 is 1
