Given numbers are 389, 670, 637, 415

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

Apply this formula for all numbers.

Step1:

LCM(389, 670) = 260630

GCD(389, 670) = ( 389 x 670 ) / 260630

= 389 / 670

= 389

Step2:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

Step3:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

So, Greatest Common Divisor of 389, 670, 637, 415 is 1
