Given numbers are 775,720,516,780

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

The LCM of 775,720,516,780 is 62384400.

Find LCM of 775,720,516,780 with Prime Factorization

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

2 x 2 x 3 x 5 x 155 x 12 x 43 x 13 = 62384400

Therefore, the lowest common multiple of 775,720,516,780 is 62384400.

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.

775 x 720 x 516 x 780 = 224583840000

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.

775 : 1, 5, 25, 31, 155, 775

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

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,720,516,780, is 1.

Now, the common factors can be found like this.

775:5x 5x 31

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

516:2x 2x 3x 43

780:2x 2x 3x 5x 13

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 3x 3x 5x 5 = 3600

Therefore, the value for common factors is 3600.

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 = 224583840000/(1x3600)

LCM = 224583840000/3600

LCM = 62384400

Thus, we can understand that the LCM of 775,720,516,780 is 62384400.
