Given numbers are 415, 402, 768, 878

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 402 are 2 x 3 x 67

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 878 are 2 x 439

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

Given numbers are 415, 402, 768, 878

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

Apply this formula for all numbers.

Step1:

LCM(415, 402) = 166830

GCD(415, 402) = ( 415 x 402 ) / 166830

= 415 / 402

= 415

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 415, 402, 768, 878 is 1
