Given numbers are 515,536,920,644

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

The LCM of 515,536,920,644 is 44442440.

Find LCM of 515,536,920,644 with Prime Factorization

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

2 x 2 x 2 x 5 x 23 x 103 x 67 x 1 x 7 = 44442440

Therefore, the lowest common multiple of 515,536,920,644 is 44442440.

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.

515 x 536 x 920 x 644 = 163548179200

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.

515 : 1, 5, 103, 515

536 : 1, 2, 4, 8, 67, 134, 268, 536

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,536,920,644, is 1.

Now, the common factors can be found like this.

515:5x 103

536:2x 2x 2x 67

920:2x 2x 2x 5x 23

644:2x 2x 7x 23

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

2x 2x 2x 2x 2x 5x 23 = 3680

Therefore, the value for common factors is 3680.

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 = 163548179200/(1x3680)

LCM = 163548179200/3680

LCM = 44442440

Thus, we can understand that the LCM of 515,536,920,644 is 44442440.
