Given numbers are 644, 144, 43, 841

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

Apply this formula for all numbers.

Step1:

LCM(644, 144) = 23184

GCD(644, 144) = ( 644 x 144 ) / 23184

= 644 / 144

= 644

Step2:

LCM(4, 43) = 172

GCD(4, 43) = ( 4 x 43 ) / 172

= 4 / 43

= 4

Step3:

LCM(1, 841) = 841

GCD(1, 841) = ( 1 x 841 ) / 841

= 1 / 841

= 1

So, Greatest Common Divisor of 644, 144, 43, 841 is 1
