Given numbers are 520,143,780,619

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

The LCM of 520,143,780,619 is 10622040.

Find LCM of 520,143,780,619 with Prime Factorization

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

2 x 2 x 5 x 13 x 2 x 11 x 3 x 619 = 10622040

Therefore, the lowest common multiple of 520,143,780,619 is 10622040.

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.

520 x 143 x 780 x 619 = 35902495200

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

143 : 1, 11, 13, 143

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

619 : 1, 619

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,143,780,619, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

143:11x 13

780:2x 2x 3x 5x 13

619:619

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 5x 13x 13 = 3380

Therefore, the value for common factors is 3380.

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 = 35902495200/(1x3380)

LCM = 35902495200/3380

LCM = 10622040

Thus, we can understand that the LCM of 520,143,780,619 is 10622040.
