Given numbers are 439,403,420,658

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

The LCM of 439,403,420,658 is 3492341580.

Find LCM of 439,403,420,658 with Prime Factorization

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

2 x 7 x 439 x 403 x 30 x 47 = 3492341580

Therefore, the lowest common multiple of 439,403,420,658 is 3492341580.

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 403 x 420 x 658 = 48892782120

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

403 : 1, 13, 31, 403

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

658 : 1, 2, 7, 14, 47, 94, 329, 658

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,403,420,658, is 1.

Now, the common factors can be found like this.

439:439

403:13x 31

420:2x 2x 3x 5x 7

658:2x 7x 47

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 48892782120/(1x14)

LCM = 48892782120/14

LCM = 3492341580

Thus, we can understand that the LCM of 439,403,420,658 is 3492341580.
