Given numbers are 787, 218, 439, 351

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

Apply this formula for all numbers.

Step1:

LCM(787, 218) = 171566

GCD(787, 218) = ( 787 x 218 ) / 171566

= 787 / 218

= 787

Step2:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

Step3:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

So, Greatest Common Divisor of 787, 218, 439, 351 is 1
