Given numbers are 555, 815, 778

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

Apply this formula for all numbers.

Step1:

LCM(555, 815) = 90465

GCD(555, 815) = ( 555 x 815 ) / 90465

= 555 / 815

= 555

Step2:

LCM(5, 778) = 3890

GCD(5, 778) = ( 5 x 778 ) / 3890

= 5 / 778

= 5

So, Greatest Common Divisor of 555, 815, 778 is 1
