Given numbers are 920,988,641,228,376

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

The LCM of 920,988,641,228,376 is 20538178440.

Find LCM of 920,988,641,228,376 with Prime Factorization

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

2 x 2 x 2 x 19 x 115 x 13 x 641 x 3 x 47 = 20538178440

Therefore, the lowest common multiple of 920,988,641,228,376 is 20538178440.

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.

920 x 988 x 641 x 228 x 376 = 49948849966080

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

641 : 1, 641

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

376 : 1, 2, 4, 8, 47, 94, 188, 376

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,988,641,228,376, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

988:2x 2x 13x 19

641:641

228:2x 2x 3x 19

376:2x 2x 2x 47

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 2x 2x 19 = 2432

Therefore, the value for common factors is 2432.

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 = 49948849966080/(1x2432)

LCM = 49948849966080/2432

LCM = 20538178440

Thus, we can understand that the LCM of 920,988,641,228,376 is 20538178440.
