Given numbers are 399, 777, 919, 242

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

Apply this formula for all numbers.

Step1:

LCM(399, 777) = 14763

GCD(399, 777) = ( 399 x 777 ) / 14763

= 399 / 777

= 399

Step2:

LCM(21, 919) = 19299

GCD(21, 919) = ( 21 x 919 ) / 19299

= 21 / 919

= 21

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 399, 777, 919, 242 is 1
