Given numbers are 399,437,974,712,720

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

The LCM of 399,437,974,712,720 is 95462090640.

Find LCM of 399,437,974,712,720 with Prime Factorization

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

2 x 2 x 2 x 3 x 19 x 7 x 23 x 487 x 89 x 30 = 95462090640

Therefore, the lowest common multiple of 399,437,974,712,720 is 95462090640.

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.

399 x 437 x 974 x 712 x 720 = 87061426663680

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

437 : 1, 19, 23, 437

974 : 1, 2, 487, 974

712 : 1, 2, 4, 8, 89, 178, 356, 712

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,437,974,712,720, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

437:19x 23

974:2x 487

712:2x 2x 2x 89

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

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 19 = 912

Therefore, the value for common factors is 912.

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 = 87061426663680/(1x912)

LCM = 87061426663680/912

LCM = 95462090640

Thus, we can understand that the LCM of 399,437,974,712,720 is 95462090640.
