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

Apply this formula for all numbers.

Step1:

LCM(278, 554) = 77006

GCD(278, 554) = ( 278 x 554 ) / 77006

= 278 / 554

= 278

Step2:

LCM(2, 686) = 686

GCD(2, 686) = ( 2 x 686 ) / 686

= 2 / 686

= 2

Step3:

LCM(2, 544) = 544

GCD(2, 544) = ( 2 x 544 ) / 544

= 2 / 544

= 2

So, Greatest Common Divisor of 278, 554, 686, 544 is 2
