Given numbers are 247, 423, 334, 842

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

Apply this formula for all numbers.

Step1:

LCM(247, 423) = 104481

GCD(247, 423) = ( 247 x 423 ) / 104481

= 247 / 423

= 247

Step2:

LCM(1, 334) = 334

GCD(1, 334) = ( 1 x 334 ) / 334

= 1 / 334

= 1

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 247, 423, 334, 842 is 1
