Given numbers are 561, 363, 946, 181

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

Apply this formula for all numbers.

Step1:

LCM(561, 363) = 6171

GCD(561, 363) = ( 561 x 363 ) / 6171

= 561 / 363

= 561

Step2:

LCM(33, 946) = 2838

GCD(33, 946) = ( 33 x 946 ) / 2838

= 33 / 946

= 33

Step3:

LCM(11, 181) = 1991

GCD(11, 181) = ( 11 x 181 ) / 1991

= 11 / 181

= 11

So, Greatest Common Divisor of 561, 363, 946, 181 is 1
