Given numbers are 943, 647, 881, 561

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

Apply this formula for all numbers.

Step1:

LCM(943, 647) = 610121

GCD(943, 647) = ( 943 x 647 ) / 610121

= 943 / 647

= 943

Step2:

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

= 1 / 881

= 1

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 943, 647, 881, 561 is 1
