Given numbers are 531,326,156,821

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

The LCM of 531,326,156,821 is 3695120676.

Find LCM of 531,326,156,821 with Prime Factorization

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

2 x 3 x 177 x 163 x 26 x 821 = 3695120676

Therefore, the lowest common multiple of 531,326,156,821 is 3695120676.

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.

531 x 326 x 156 x 821 = 22170724056

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.

531 : 1, 3, 9, 59, 177, 531

326 : 1, 2, 163, 326

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,326,156,821, is 1.

Now, the common factors can be found like this.

531:3x 3x 59

326:2x 163

156:2x 2x 3x 13

821:821

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 22170724056/(1x6)

LCM = 22170724056/6

LCM = 3695120676

Thus, we can understand that the LCM of 531,326,156,821 is 3695120676.
