What is LCM of 428 and 434

Given Numbers are 428, 434

We can find the LCM of 428, 434 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 428 and 434

Multiples of 428 =428,856,1284,1712,2140,2568,2996,3424,3852,4280,4708,5136,5564,5992,6420,6848,7276,

Multiples of 434 =434,868,1302,1736,2170,2604,3038,3472,3906,4340,4774,5208,5642,6076,6510,6944,7378,

Now, get the least common multiple of 428, 434 which is 92876

So, the LCM of 428, 434 is 92876.

Least Common Multiple (LCM) of 428 and 434 with the help of Prime Factorisation

One method for determining the LCM of 428 and 434 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:

Here is 428's prime factorization:


2 428
2 214
107 107
1

Prime factors of 428 are 2,107.

428 = 22×1071

And this is 434's prime factorization:


2 434
7 217
31 31
1

Prime factors of 434 are 2, 7,31.

434 = 21×71×311

When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered: 2,107, 7,31

.

22×71×311×1071 = 92876

This shows that the LCM of 428 and 434 is 92876.

How to Calculate the LCM of 428 and 434 Using Common Multiples
