Given numbers are 938,408,923,668,620

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

The LCM of 938,408,923,668,620 is 4571754237960.

Find LCM of 938,408,923,668,620 with Prime Factorization

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

2 x 2 x 469 x 102 x 923 x 167 x 155 = 4571754237960

Therefore, the lowest common multiple of 938,408,923,668,620 is 4571754237960.

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.

938 x 408 x 923 x 668 x 620 = 146296135614720

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.

938 : 1, 2, 7, 14, 67, 134, 469, 938

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

923 : 1, 13, 71, 923

668 : 1, 2, 4, 167, 334, 668

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,408,923,668,620, is 1.

Now, the common factors can be found like this.

938:2x 7x 67

408:2x 2x 2x 3x 17

923:13x 71

668:2x 2x 167

620:2x 2x 5x 31

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 2 = 32

Therefore, the value for common factors is 32.

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 = 146296135614720/(1x32)

LCM = 146296135614720/32

LCM = 4571754237960

Thus, we can understand that the LCM of 938,408,923,668,620 is 4571754237960.
