Given numbers are 691,357,445,780

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

The LCM of 691,357,445,780 is 5708337180.

Find LCM of 691,357,445,780 with Prime Factorization

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

3 x 5 x 691 x 119 x 89 x 52 = 5708337180

Therefore, the lowest common multiple of 691,357,445,780 is 5708337180.

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.

691 x 357 x 445 x 780 = 85625057700

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.

691 : 1, 691

357 : 1, 3, 7, 17, 21, 51, 119, 357

445 : 1, 5, 89, 445

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,357,445,780, is 1.

Now, the common factors can be found like this.

691:691

357:3x 7x 17

445:5x 89

780:2x 2x 3x 5x 13

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 85625057700/(1x15)

LCM = 85625057700/15

LCM = 5708337180

Thus, we can understand that the LCM of 691,357,445,780 is 5708337180.
