Given numbers are 103,430,344,742

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

The LCM of 103,430,344,742 is 65726360.

Find LCM of 103,430,344,742 with Prime Factorization

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

2 x 43 x 103 x 5 x 4 x 371 = 65726360

Therefore, the lowest common multiple of 103,430,344,742 is 65726360.

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.

103 x 430 x 344 x 742 = 11304933920

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.

103 : 1, 103

430 : 1, 2, 5, 10, 43, 86, 215, 430

344 : 1, 2, 4, 8, 43, 86, 172, 344

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,430,344,742, is 1.

Now, the common factors can be found like this.

103:103

430:2x 5x 43

344:2x 2x 2x 43

742:2x 7x 53

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 43 = 172

Therefore, the value for common factors is 172.

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 = 11304933920/(1x172)

LCM = 11304933920/172

LCM = 65726360

Thus, we can understand that the LCM of 103,430,344,742 is 65726360.
