Given numbers are 780,918,651,357,849

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

The LCM of 780,918,651,357,849 is 7328788740.

Find LCM of 780,918,651,357,849 with Prime Factorization

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

2 x 3 x 7 x 17 x 130 x 9 x 31 x 1 x 283 = 7328788740

Therefore, the lowest common multiple of 780,918,651,357,849 is 7328788740.

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.

780 x 918 x 651 x 357 x 849 = 141284389329720

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.

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

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

651 : 1, 3, 7, 21, 31, 93, 217, 651

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

849 : 1, 3, 283, 849

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,918,651,357,849, is 3.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

918:2x 3x 3x 3x 17

651:3x 7x 31

357:3x 7x 17

849:3x 283

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 7x 17 = 6426

Therefore, the value for common factors is 6426.

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 = 141284389329720/(3x6426)

LCM = 141284389329720/19278

LCM = 7328788740

Thus, we can understand that the LCM of 780,918,651,357,849 is 7328788740.
