Given numbers are 378, 510, 128, 788

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

Apply this formula for all numbers.

Step1:

LCM(378, 510) = 32130

GCD(378, 510) = ( 378 x 510 ) / 32130

= 378 / 510

= 378

Step2:

LCM(6, 128) = 384

GCD(6, 128) = ( 6 x 128 ) / 384

= 6 / 128

= 6

Step3:

LCM(2, 788) = 788

GCD(2, 788) = ( 2 x 788 ) / 788

= 2 / 788

= 2

So, Greatest Common Divisor of 378, 510, 128, 788 is 2
