Given numbers are 755, 245, 205, 891

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

Apply this formula for all numbers.

Step1:

LCM(755, 245) = 36995

GCD(755, 245) = ( 755 x 245 ) / 36995

= 755 / 245

= 755

Step2:

LCM(5, 205) = 205

GCD(5, 205) = ( 5 x 205 ) / 205

= 5 / 205

= 5

Step3:

LCM(5, 891) = 4455

GCD(5, 891) = ( 5 x 891 ) / 4455

= 5 / 891

= 5

So, Greatest Common Divisor of 755, 245, 205, 891 is 1
