Given numbers are 245, 320, 379, 221

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

Apply this formula for all numbers.

Step1:

LCM(245, 320) = 15680

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

= 245 / 320

= 245

Step2:

LCM(5, 379) = 1895

GCD(5, 379) = ( 5 x 379 ) / 1895

= 5 / 379

= 5

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 245, 320, 379, 221 is 1
