Given numbers are 742,557,355,557

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

The LCM of 742,557,355,557 is 146719370.

Find LCM of 742,557,355,557 with Prime Factorization

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

557 x 742 x 1 x 355 x 1 = 146719370

Therefore, the lowest common multiple of 742,557,355,557 is 146719370.

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 557 x 355 x 557 = 81722689090

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

557 : 1, 557

355 : 1, 5, 71, 355

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,557,355,557, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

557:557

355:5x 71

557:557

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

557 = 557

Therefore, the value for common factors is 557.

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 = 81722689090/(1x557)

LCM = 81722689090/557

LCM = 146719370

Thus, we can understand that the LCM of 742,557,355,557 is 146719370.
