Given numbers are 687, 235, 391, 901

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

Apply this formula for all numbers.

Step1:

LCM(687, 235) = 161445

GCD(687, 235) = ( 687 x 235 ) / 161445

= 687 / 235

= 687

Step2:

LCM(1, 391) = 391

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

= 1 / 391

= 1

Step3:

LCM(1, 901) = 901

GCD(1, 901) = ( 1 x 901 ) / 901

= 1 / 901

= 1

So, Greatest Common Divisor of 687, 235, 391, 901 is 1
