Given numbers are 440,953,770,420

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

The LCM of 440,953,770,420 is 8805720.

Find LCM of 440,953,770,420 with Prime Factorization

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

2 x 2 x 5 x 7 x 11 x 2 x 953 x 1 x 3 = 8805720

Therefore, the lowest common multiple of 440,953,770,420 is 8805720.

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.

440 x 953 x 770 x 420 = 135608088000

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.

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

953 : 1, 953

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,953,770,420, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

953:953

770:2x 5x 7x 11

420:2x 2x 3x 5x 7

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 5x 7x 11 = 15400

Therefore, the value for common factors is 15400.

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 = 135608088000/(1x15400)

LCM = 135608088000/15400

LCM = 8805720

Thus, we can understand that the LCM of 440,953,770,420 is 8805720.
