Given numbers are 644, 819, 886, 845

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

Apply this formula for all numbers.

Step1:

LCM(644, 819) = 75348

GCD(644, 819) = ( 644 x 819 ) / 75348

= 644 / 819

= 644

Step2:

LCM(7, 886) = 6202

GCD(7, 886) = ( 7 x 886 ) / 6202

= 7 / 886

= 7

Step3:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

So, Greatest Common Divisor of 644, 819, 886, 845 is 1
