Given numbers are 554, 661, 18

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

Apply this formula for all numbers.

Step1:

LCM(554, 661) = 366194

GCD(554, 661) = ( 554 x 661 ) / 366194

= 554 / 661

= 554

Step2:

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

= 1 / 18

= 1

So, Greatest Common Divisor of 554, 661, 18 is 1
