Given numbers are 245, 568, 820, 279

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

Apply this formula for all numbers.

Step1:

LCM(245, 568) = 139160

GCD(245, 568) = ( 245 x 568 ) / 139160

= 245 / 568

= 245

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

= 1 / 279

= 1

So, Greatest Common Divisor of 245, 568, 820, 279 is 1
