Given numbers are 561, 837, 866, 154

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

Apply this formula for all numbers.

Step1:

LCM(561, 837) = 156519

GCD(561, 837) = ( 561 x 837 ) / 156519

= 561 / 837

= 561

Step2:

LCM(3, 866) = 2598

GCD(3, 866) = ( 3 x 866 ) / 2598

= 3 / 866

= 3

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 561, 837, 866, 154 is 1
