Given numbers are 742,973,445,442,406

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

The LCM of 742,973,445,442,406 is 294150091690.

Find LCM of 742,973,445,442,406 with Prime Factorization

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

2 x 7 x 53 x 139 x 445 x 221 x 29 = 294150091690

Therefore, the lowest common multiple of 742,973,445,442,406 is 294150091690.

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.

742 x 973 x 445 x 442 x 406 = 57653417971240

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

973 : 1, 7, 139, 973

445 : 1, 5, 89, 445

442 : 1, 2, 13, 17, 26, 34, 221, 442

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,973,445,442,406, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

973:7x 139

445:5x 89

442:2x 13x 17

406:2x 7x 29

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 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 57653417971240/(1x196)

LCM = 57653417971240/196

LCM = 294150091690

Thus, we can understand that the LCM of 742,973,445,442,406 is 294150091690.
