474 is an even number, so it can be branched into 2 and 237 The sum of digits in 237 (2+3+7 = 12) is divisible by 3, so the next branch should be 3 and 79. Since 79 is a prime number, you cannot simplify it anymore, thus your final branches will be 2, 3, and 79. 474 2 x 237 2 x 3 x 79
To convert from mega electronvolts (MeV) to joules, you can use the conversion factor 1 MeV = 1.602 x 10^-13 joules. So, to convert 474 MeV to joules: 474 MeV * 1.602 x 10^-13 joules = 7.595 x 10^-11 joules.
