Given numbers are 840,578,326,469

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

The LCM of 840,578,326,469 is 2651181960.

Find LCM of 840,578,326,469 with Prime Factorization

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

2 x 7 x 60 x 289 x 163 x 67 = 2651181960

Therefore, the lowest common multiple of 840,578,326,469 is 2651181960.

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.

840 x 578 x 326 x 469 = 74233094880

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.

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

578 : 1, 2, 17, 34, 289, 578

326 : 1, 2, 163, 326

469 : 1, 7, 67, 469

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,578,326,469, is 1.

Now, the common factors can be found like this.

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

578:2x 17x 17

326:2x 163

469:7x 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 7 = 28

Therefore, the value for common factors is 28.

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 = 74233094880/(1x28)

LCM = 74233094880/28

LCM = 2651181960

Thus, we can understand that the LCM of 840,578,326,469 is 2651181960.
