Given numbers are 348,202,638,431

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

The LCM of 348,202,638,431 is 166636668.

Find LCM of 348,202,638,431 with Prime Factorization

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

2 x 29 x 6 x 101 x 11 x 431 = 166636668

Therefore, the lowest common multiple of 348,202,638,431 is 166636668.

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.

348 x 202 x 638 x 431 = 19329853488

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.

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

202 : 1, 2, 101, 202

638 : 1, 2, 11, 22, 29, 58, 319, 638

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 348,202,638,431, is 1.

Now, the common factors can be found like this.

348:2x 2x 3x 29

202:2x 101

638:2x 11x 29

431:431

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 29 = 116

Therefore, the value for common factors is 116.

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 = 19329853488/(1x116)

LCM = 19329853488/116

LCM = 166636668

Thus, we can understand that the LCM of 348,202,638,431 is 166636668.
