Given numbers are 815, 656, 245, 899

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

Apply this formula for all numbers.

Step1:

LCM(815, 656) = 534640

GCD(815, 656) = ( 815 x 656 ) / 534640

= 815 / 656

= 815

Step2:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

Step3:

LCM(1, 899) = 899

GCD(1, 899) = ( 1 x 899 ) / 899

= 1 / 899

= 1

So, Greatest Common Divisor of 815, 656, 245, 899 is 1
