Given numbers are 551,378,742,440,168

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

The LCM of 551,378,742,440,168 is 2428521480.

Find LCM of 551,378,742,440,168 with Prime Factorization

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

2 x 2 x 2 x 3 x 7 x 551 x 9 x 53 x 55 x 1 = 2428521480

Therefore, the lowest common multiple of 551,378,742,440,168 is 2428521480.

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.

551 x 378 x 742 x 440 x 168 = 11423765041920

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.

551 : 1, 19, 29, 551

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,378,742,440,168, is 1.

Now, the common factors can be found like this.

551:19x 29

378:2x 3x 3x 3x 7

742:2x 7x 53

440:2x 2x 2x 5x 11

168:2x 2x 2x 3x 7

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 2x 2x 2x 3x 7x 7 = 4704

Therefore, the value for common factors is 4704.

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 = 11423765041920/(1x4704)

LCM = 11423765041920/4704

LCM = 2428521480

Thus, we can understand that the LCM of 551,378,742,440,168 is 2428521480.
