Given numbers are 758,721,440,648

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

The LCM of 758,721,440,648 is 9738950760.

Find LCM of 758,721,440,648 with Prime Factorization

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

2 x 2 x 2 x 379 x 721 x 55 x 81 = 9738950760

Therefore, the lowest common multiple of 758,721,440,648 is 9738950760.

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.

758 x 721 x 440 x 648 = 155823212160

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.

758 : 1, 2, 379, 758

721 : 1, 7, 103, 721

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,721,440,648, is 1.

Now, the common factors can be found like this.

758:2x 379

721:7x 103

440:2x 2x 2x 5x 11

648:2x 2x 2x 3x 3x 3x 3

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 2 = 16

Therefore, the value for common factors is 16.

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 = 155823212160/(1x16)

LCM = 155823212160/16

LCM = 9738950760

Thus, we can understand that the LCM of 758,721,440,648 is 9738950760.
