Given numbers are 357, 123, 842, 308

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

Apply this formula for all numbers.

Step1:

LCM(357, 123) = 14637

GCD(357, 123) = ( 357 x 123 ) / 14637

= 357 / 123

= 357

Step2:

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

= 3 / 842

= 3

Step3:

LCM(1, 308) = 308

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

= 1 / 308

= 1

So, Greatest Common Divisor of 357, 123, 842, 308 is 1
