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

Multiples of 438 =438,876,1314,1752,2190,2628,3066,3504,3942,4380,4818,5256,5694,6132,6570,7008,7446,

Now, get the least common multiple of 434, 438 which is 95046

So, the LCM of 434, 438 is 95046.

One method for determining the LCM of 434 and 438 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 434's prime factorization:

Prime factors of 434 are 2, 7,31.

434 = 2¹×7¹×31¹

And this is 438's prime factorization:

Prime factors of 438 are 2, 3,73.

438 = 2¹×3¹×73¹

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, 7,31, 3,73

2¹×3¹×7¹×31¹×73¹ = 95046

This shows that the LCM of 434 and 438 is 95046.

The first step in determining the Least Common Multiple of 434 and 438 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 434 and 438:

Lets look at the first ten multiples of these numbers, 434 and 438:

434,868,1302,1736,2170,2604,3038,3472,3906,7378 are the first ten multiples of 434.

438,876,1314,1752,2190,2628,3066,3504,3942,7446 are the first ten multiples of 438.

You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 434 and 438, for example, are 5208, 7378, and 7008. 95046 is the least common multiple since it is the smallest.

434 and 438 have an LCM of 95046.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 434 and 438, than apply into the LCM equation.

GCF(434,438) = 2
LCM(434,438) = ( 434 × 438) / 2
LCM(434,438) = 190092 / 2
LCM(434,438) = 95046
