Given numbers are 743, 279, 671, 644

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

Apply this formula for all numbers.

Step1:

LCM(743, 279) = 207297

GCD(743, 279) = ( 743 x 279 ) / 207297

= 743 / 279

= 743

Step2:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

Step3:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 743, 279, 671, 644 is 1
