Given numbers are 920,507,720,497

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

The LCM of 920,507,720,497 is 1390924080.

Find LCM of 920,507,720,497 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 23 x 169 x 6 x 497 = 1390924080

Therefore, the lowest common multiple of 920,507,720,497 is 1390924080.

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.

920 x 507 x 720 x 497 = 166910889600

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

507 : 1, 3, 13, 39, 169, 507

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,507,720,497, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

507:3x 13x 13

720:2x 2x 2x 2x 3x 3x 5

497:7x 71

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 5 = 120

Therefore, the value for common factors is 120.

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 = 166910889600/(1x120)

LCM = 166910889600/120

LCM = 1390924080

Thus, we can understand that the LCM of 920,507,720,497 is 1390924080.
