Given numbers are 345, 825, 655, 903

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

Apply this formula for all numbers.

Step1:

LCM(345, 825) = 18975

GCD(345, 825) = ( 345 x 825 ) / 18975

= 345 / 825

= 345

Step2:

LCM(15, 655) = 1965

GCD(15, 655) = ( 15 x 655 ) / 1965

= 15 / 655

= 15

Step3:

LCM(5, 903) = 4515

GCD(5, 903) = ( 5 x 903 ) / 4515

= 5 / 903

= 5

So, Greatest Common Divisor of 345, 825, 655, 903 is 1
