Given numbers are 780,580,348,974

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

The LCM of 780,580,348,974 is 11015940.

Find LCM of 780,580,348,974 with Prime Factorization

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

2 x 2 x 3 x 5 x 29 x 13 x 1 x 1 x 487 = 11015940

Therefore, the lowest common multiple of 780,580,348,974 is 11015940.

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 580 x 348 x 974 = 153341884800

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

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

974 : 1, 2, 487, 974

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,580,348,974, is 2.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

580:2x 2x 5x 29

348:2x 2x 3x 29

974:2x 487

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 5x 29 = 6960

Therefore, the value for common factors is 6960.

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 = 153341884800/(2x6960)

LCM = 153341884800/13920

LCM = 11015940

Thus, we can understand that the LCM of 780,580,348,974 is 11015940.
