Given numbers are 766, 421, 100, 408

The list of prime factors of all numbers are

Prime factors of 766 are 2 x 383

Prime factors of 421 are 421

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 766, 421, 100, 408

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

Apply this formula for all numbers.

Step1:

LCM(766, 421) = 322486

GCD(766, 421) = ( 766 x 421 ) / 322486

= 766 / 421

= 766

Step2:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 766, 421, 100, 408 is 1
