Given numbers are 768, 216, 99, 407

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

Apply this formula for all numbers.

Step1:

LCM(768, 216) = 6912

GCD(768, 216) = ( 768 x 216 ) / 6912

= 768 / 216

= 768

Step2:

LCM(24, 99) = 792

GCD(24, 99) = ( 24 x 99 ) / 792

= 24 / 99

= 24

Step3:

LCM(3, 407) = 1221

GCD(3, 407) = ( 3 x 407 ) / 1221

= 3 / 407

= 3

So, Greatest Common Divisor of 768, 216, 99, 407 is 1
