Given numbers are 415, 686, 96, 391

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

Apply this formula for all numbers.

Step1:

LCM(415, 686) = 284690

GCD(415, 686) = ( 415 x 686 ) / 284690

= 415 / 686

= 415

Step2:

LCM(1, 96) = 96

GCD(1, 96) = ( 1 x 96 ) / 96

= 1 / 96

= 1

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 415, 686, 96, 391 is 1
