Given numbers are 245, 309, 308, 541

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

Apply this formula for all numbers.

Step1:

LCM(245, 309) = 75705

GCD(245, 309) = ( 245 x 309 ) / 75705

= 245 / 309

= 245

Step2:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

Step3:

LCM(1, 541) = 541

GCD(1, 541) = ( 1 x 541 ) / 541

= 1 / 541

= 1

So, Greatest Common Divisor of 245, 309, 308, 541 is 1
