Given numbers are 431,131,326,917

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 431,131,326,917 is 128844002.

Find LCM of 431,131,326,917 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

131 x 431 x 1 x 326 x 7 = 128844002

Therefore, the lowest common multiple of 431,131,326,917 is 128844002.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

431 x 131 x 326 x 917 = 16878564262

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

431 : 1, 431

131 : 1, 131

326 : 1, 2, 163, 326

917 : 1, 7, 131, 917

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,131,326,917, is 1.

Now, the common factors can be found like this.

431:431

131:131

326:2x 163

917:7x 131

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

131 = 131

Therefore, the value for common factors is 131.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 16878564262/(1x131)

LCM = 16878564262/131

LCM = 128844002

Thus, we can understand that the LCM of 431,131,326,917 is 128844002.
