Given numbers are 890,440,430,638,940

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

The LCM of 890,440,430,638,940 is 2295128440.

Find LCM of 890,440,430,638,940 with Prime Factorization

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

2 x 2 x 5 x 11 x 89 x 2 x 43 x 29 x 47 = 2295128440

Therefore, the lowest common multiple of 890,440,430,638,940 is 2295128440.

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.

890 x 440 x 430 x 638 x 940 = 100985651360000

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.

890 : 1, 2, 5, 10, 89, 178, 445, 890

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

430 : 1, 2, 5, 10, 43, 86, 215, 430

638 : 1, 2, 11, 22, 29, 58, 319, 638

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,440,430,638,940, is 2.

Now, the common factors can be found like this.

890:2x 5x 89

440:2x 2x 2x 5x 11

430:2x 5x 43

638:2x 11x 29

940:2x 2x 5x 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 5x 5x 5x 11 = 22000

Therefore, the value for common factors is 22000.

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 = 100985651360000/(2x22000)

LCM = 100985651360000/44000

LCM = 2295128440

Thus, we can understand that the LCM of 890,440,430,638,940 is 2295128440.
