Given numbers are 643, 841, 695, 912

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

Apply this formula for all numbers.

Step1:

LCM(643, 841) = 540763

GCD(643, 841) = ( 643 x 841 ) / 540763

= 643 / 841

= 643

Step2:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1

Step3:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

So, Greatest Common Divisor of 643, 841, 695, 912 is 1
