Given numbers are 429,431,131,917

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

The LCM of 429,431,131,917 is 169552383.

Find LCM of 429,431,131,917 with Prime Factorization

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

131 x 429 x 431 x 1 x 7 = 169552383

Therefore, the lowest common multiple of 429,431,131,917 is 169552383.

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.

429 x 431 x 131 x 917 = 22211362173

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.

429 : 1, 3, 11, 13, 33, 39, 143, 429

431 : 1, 431

131 : 1, 131

917 : 1, 7, 131, 917

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,431,131,917, is 1.

Now, the common factors can be found like this.

429:3x 11x 13

431:431

131:131

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 = 22211362173/(1x131)

LCM = 22211362173/131

LCM = 169552383

Thus, we can understand that the LCM of 429,431,131,917 is 169552383.
