Given numbers are 959, 644, 407, 623

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

Apply this formula for all numbers.

Step1:

LCM(959, 644) = 88228

GCD(959, 644) = ( 959 x 644 ) / 88228

= 959 / 644

= 959

Step2:

LCM(7, 407) = 2849

GCD(7, 407) = ( 7 x 407 ) / 2849

= 7 / 407

= 7

Step3:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

So, Greatest Common Divisor of 959, 644, 407, 623 is 1
