Given numbers are 245, 815, 991, 301

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

Apply this formula for all numbers.

Step1:

LCM(245, 815) = 39935

GCD(245, 815) = ( 245 x 815 ) / 39935

= 245 / 815

= 245

Step2:

LCM(5, 991) = 4955

GCD(5, 991) = ( 5 x 991 ) / 4955

= 5 / 991

= 5

Step3:

LCM(1, 301) = 301

GCD(1, 301) = ( 1 x 301 ) / 301

= 1 / 301

= 1

So, Greatest Common Divisor of 245, 815, 991, 301 is 1
