Given numbers are 960,996,721,247,391

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

The LCM of 960,996,721,247,391 is 5548279114560.

Find LCM of 960,996,721,247,391 with Prime Factorization

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

2 x 2 x 3 x 80 x 83 x 721 x 247 x 391 = 5548279114560

Therefore, the lowest common multiple of 960,996,721,247,391 is 5548279114560.

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.

960 x 996 x 721 x 247 x 391 = 66579349374720

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.

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

721 : 1, 7, 103, 721

247 : 1, 13, 19, 247

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 960,996,721,247,391, is 1.

Now, the common factors can be found like this.

960:2x 2x 2x 2x 2x 2x 3x 5

996:2x 2x 3x 83

721:7x 103

247:13x 19

391:17x 23

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 3 = 12

Therefore, the value for common factors is 12.

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 = 66579349374720/(1x12)

LCM = 66579349374720/12

LCM = 5548279114560

Thus, we can understand that the LCM of 960,996,721,247,391 is 5548279114560.
