Given numbers are 424,742,881,391

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

The LCM of 424,742,881,391 is 1022389928.

Find LCM of 424,742,881,391 with Prime Factorization

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

2 x 53 x 4 x 7 x 881 x 391 = 1022389928

Therefore, the lowest common multiple of 424,742,881,391 is 1022389928.

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.

424 x 742 x 881 x 391 = 108373332368

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.

424 : 1, 2, 4, 8, 53, 106, 212, 424

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

881 : 1, 881

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,742,881,391, is 1.

Now, the common factors can be found like this.

424:2x 2x 2x 53

742:2x 7x 53

881:881

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 53 = 106

Therefore, the value for common factors is 106.

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 = 108373332368/(1x106)

LCM = 108373332368/106

LCM = 1022389928

Thus, we can understand that the LCM of 424,742,881,391 is 1022389928.
