Given numbers are 826,464,637,420,673

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

The LCM of 826,464,637,420,673 is 176041778640.

Find LCM of 826,464,637,420,673 with Prime Factorization

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

2 x 2 x 7 x 59 x 116 x 91 x 15 x 673 = 176041778640

Therefore, the lowest common multiple of 826,464,637,420,673 is 176041778640.

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.

826 x 464 x 637 x 420 x 673 = 69008377226880

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.

826 : 1, 2, 7, 14, 59, 118, 413, 826

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

637 : 1, 7, 13, 49, 91, 637

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

673 : 1, 673

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,464,637,420,673, is 1.

Now, the common factors can be found like this.

826:2x 7x 59

464:2x 2x 2x 2x 29

637:7x 7x 13

420:2x 2x 3x 5x 7

673:673

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 7x 7 = 392

Therefore, the value for common factors is 392.

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 = 69008377226880/(1x392)

LCM = 69008377226880/392

LCM = 176041778640

Thus, we can understand that the LCM of 826,464,637,420,673 is 176041778640.
