Given numbers are 515,676,420,740,720

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

The LCM of 515,676,420,740,720 is 3246057360.

Find LCM of 515,676,420,740,720 with Prime Factorization

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

2 x 2 x 3 x 5 x 103 x 169 x 7 x 37 x 12 = 3246057360

Therefore, the lowest common multiple of 515,676,420,740,720 is 3246057360.

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.

515 x 676 x 420 x 740 x 720 = 77905376640000

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.

515 : 1, 5, 103, 515

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

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

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,676,420,740,720, is 1.

Now, the common factors can be found like this.

515:5x 103

676:2x 2x 13x 13

420:2x 2x 3x 5x 7

740:2x 2x 5x 37

720:2x 2x 2x 2x 3x 3x 5

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 3x 5x 5x 5 = 24000

Therefore, the value for common factors is 24000.

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 = 77905376640000/(1x24000)

LCM = 77905376640000/24000

LCM = 3246057360

Thus, we can understand that the LCM of 515,676,420,740,720 is 3246057360.
