Given numbers are 780,583,910,620

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

The LCM of 780,583,910,620 is 98678580.

Find LCM of 780,583,910,620 with Prime Factorization

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

2 x 2 x 5 x 13 x 3 x 583 x 7 x 31 = 98678580

Therefore, the lowest common multiple of 780,583,910,620 is 98678580.

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.

780 x 583 x 910 x 620 = 256564308000

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

583 : 1, 11, 53, 583

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

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 780,583,910,620, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

583:11x 53

910:2x 5x 7x 13

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 5x 5x 13 = 2600

Therefore, the value for common factors is 2600.

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 = 256564308000/(1x2600)

LCM = 256564308000/2600

LCM = 98678580

Thus, we can understand that the LCM of 780,583,910,620 is 98678580.
