Given numbers are 780,669,440,375

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

The LCM of 780,669,440,375 is 95667000.

Find LCM of 780,669,440,375 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 223 x 22 x 25 = 95667000

Therefore, the lowest common multiple of 780,669,440,375 is 95667000.

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 669 x 440 x 375 = 86100300000

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

669 : 1, 3, 223, 669

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

375 : 1, 3, 5, 15, 25, 75, 125, 375

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,669,440,375, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

669:3x 223

440:2x 2x 2x 5x 11

375:3x 5x 5x 5

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 3x 3x 5x 5 = 900

Therefore, the value for common factors is 900.

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 = 86100300000/(1x900)

LCM = 86100300000/900

LCM = 95667000

Thus, we can understand that the LCM of 780,669,440,375 is 95667000.
