Given numbers are 320, 245, 89, 821

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

Apply this formula for all numbers.

Step1:

LCM(320, 245) = 15680

GCD(320, 245) = ( 320 x 245 ) / 15680

= 320 / 245

= 320

Step2:

LCM(5, 89) = 445

GCD(5, 89) = ( 5 x 89 ) / 445

= 5 / 89

= 5

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 320, 245, 89, 821 is 1
