Given numbers are 983, 393, 886, 644

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

Apply this formula for all numbers.

Step1:

LCM(983, 393) = 386319

GCD(983, 393) = ( 983 x 393 ) / 386319

= 983 / 393

= 983

Step2:

LCM(1, 886) = 886

GCD(1, 886) = ( 1 x 886 ) / 886

= 1 / 886

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 983, 393, 886, 644 is 1
