Given numbers are 439,862,780,974

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

The LCM of 439,862,780,974 is 71872930740.

Find LCM of 439,862,780,974 with Prime Factorization

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

2 x 439 x 431 x 390 x 487 = 71872930740

Therefore, the lowest common multiple of 439,862,780,974 is 71872930740.

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.

439 x 862 x 780 x 974 = 287491722960

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.

439 : 1, 439

862 : 1, 2, 431, 862

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

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,862,780,974, is 1.

Now, the common factors can be found like this.

439:439

862:2x 431

780:2x 2x 3x 5x 13

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 2 = 4

Therefore, the value for common factors is 4.

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 = 287491722960/(1x4)

LCM = 287491722960/4

LCM = 71872930740

Thus, we can understand that the LCM of 439,862,780,974 is 71872930740.
