Given numbers are 531,432,390,453,553

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

The LCM of 531,432,390,453,553 is 138341090160.

Find LCM of 531,432,390,453,553 with Prime Factorization

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

2 x 3 x 3 x 59 x 24 x 65 x 151 x 553 = 138341090160

Therefore, the lowest common multiple of 531,432,390,453,553 is 138341090160.

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 432 x 390 x 453 x 553 = 22411256605920

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

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

453 : 1, 3, 151, 453

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,432,390,453,553, is 1.

Now, the common factors can be found like this.

531:3x 3x 59

432:2x 2x 2x 2x 3x 3x 3

390:2x 3x 5x 13

453:3x 151

553:7x 79

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

2x 3x 3x 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 22411256605920/(1x162)

LCM = 22411256605920/162

LCM = 138341090160

Thus, we can understand that the LCM of 531,432,390,453,553 is 138341090160.
