Given numbers are 755, 428, 678

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

Apply this formula for all numbers.

Step1:

LCM(755, 428) = 323140

GCD(755, 428) = ( 755 x 428 ) / 323140

= 755 / 428

= 755

Step2:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 755, 428, 678 is 1
