Given numbers are 354,431,840,804

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

The LCM of 354,431,840,804 is 1431144120.

Find LCM of 354,431,840,804 with Prime Factorization

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

2 x 2 x 3 x 59 x 431 x 70 x 67 = 1431144120

Therefore, the lowest common multiple of 354,431,840,804 is 1431144120.

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.

354 x 431 x 840 x 804 = 103042376640

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.

354 : 1, 2, 3, 6, 59, 118, 177, 354

431 : 1, 431

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,431,840,804, is 1.

Now, the common factors can be found like this.

354:2x 3x 59

431:431

840:2x 2x 2x 3x 5x 7

804:2x 2x 3x 67

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 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 103042376640/(1x72)

LCM = 103042376640/72

LCM = 1431144120

Thus, we can understand that the LCM of 354,431,840,804 is 1431144120.
