Given numbers are 742,455,371,491

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

The LCM of 742,455,371,491 is 23680930.

Find LCM of 742,455,371,491 with Prime Factorization

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

7 x 53 x 2 x 65 x 1 x 491 = 23680930

Therefore, the lowest common multiple of 742,455,371,491 is 23680930.

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 455 x 371 x 491 = 61499375210

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

455 : 1, 5, 7, 13, 35, 65, 91, 455

371 : 1, 7, 53, 371

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,455,371,491, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

455:5x 7x 13

371:7x 53

491:491

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

7x 7x 53 = 2597

Therefore, the value for common factors is 2597.

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 = 61499375210/(1x2597)

LCM = 61499375210/2597

LCM = 23680930

Thus, we can understand that the LCM of 742,455,371,491 is 23680930.
