Given numbers are 670,437,644,307,920

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

The LCM of 670,437,644,307,920 is 2516822840.

Find LCM of 670,437,644,307,920 with Prime Factorization

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

2 x 2 x 5 x 23 x 67 x 19 x 7 x 307 x 2 = 2516822840

Therefore, the lowest common multiple of 670,437,644,307,920 is 2516822840.

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.

670 x 437 x 644 x 307 x 920 = 53255971294400

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

437 : 1, 19, 23, 437

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

307 : 1, 307

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,437,644,307,920, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

437:19x 23

644:2x 2x 7x 23

307:307

920:2x 2x 2x 5x 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 5x 23x 23 = 21160

Therefore, the value for common factors is 21160.

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 = 53255971294400/(1x21160)

LCM = 53255971294400/21160

LCM = 2516822840

Thus, we can understand that the LCM of 670,437,644,307,920 is 2516822840.
