Given numbers are 740,415,860,756,430

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

The LCM of 740,415,860,756,430 is 499160340.

Find LCM of 740,415,860,756,430 with Prime Factorization

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

2 x 2 x 5 x 43 x 37 x 83 x 1 x 189 x 1 = 499160340

Therefore, the lowest common multiple of 740,415,860,756,430 is 499160340.

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.

740 x 415 x 860 x 756 x 430 = 85855578480000

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.

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

415 : 1, 5, 83, 415

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,415,860,756,430, is 1.

Now, the common factors can be found like this.

740:2x 2x 5x 37

415:5x 83

860:2x 2x 5x 43

756:2x 2x 3x 3x 3x 7

430:2x 5x 43

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 5x 5x 5x 43 = 172000

Therefore, the value for common factors is 172000.

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 = 85855578480000/(1x172000)

LCM = 85855578480000/172000

LCM = 499160340

Thus, we can understand that the LCM of 740,415,860,756,430 is 499160340.
