Given numbers are 278, 386, 18, 552

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

Apply this formula for all numbers.

Step1:

LCM(278, 386) = 53654

GCD(278, 386) = ( 278 x 386 ) / 53654

= 278 / 386

= 278

Step2:

LCM(2, 18) = 18

GCD(2, 18) = ( 2 x 18 ) / 18

= 2 / 18

= 2

Step3:

LCM(2, 552) = 552

GCD(2, 552) = ( 2 x 552 ) / 552

= 2 / 552

= 2

So, Greatest Common Divisor of 278, 386, 18, 552 is 2
