Given numbers are 556, 909, 221, 146

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

Apply this formula for all numbers.

Step1:

LCM(556, 909) = 505404

GCD(556, 909) = ( 556 x 909 ) / 505404

= 556 / 909

= 556

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

So, Greatest Common Divisor of 556, 909, 221, 146 is 1
