Given numbers are 720,695,115,690,974

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

The LCM of 720,695,115,690,974 is 1120996080.

Find LCM of 720,695,115,690,974 with Prime Factorization

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

2 x 3 x 5 x 23 x 24 x 139 x 1 x 1 x 487 = 1120996080

Therefore, the lowest common multiple of 720,695,115,690,974 is 1120996080.

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.

720 x 695 x 115 x 690 x 974 = 38674364760000

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.

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

695 : 1, 5, 139, 695

115 : 1, 5, 23, 115

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,695,115,690,974, is 1.

Now, the common factors can be found like this.

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

695:5x 139

115:5x 23

690:2x 3x 5x 23

974:2x 487

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 3x 5x 5x 5x 23 = 34500

Therefore, the value for common factors is 34500.

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 = 38674364760000/(1x34500)

LCM = 38674364760000/34500

LCM = 1120996080

Thus, we can understand that the LCM of 720,695,115,690,974 is 1120996080.
