Given numbers are 351,160,310,430,620

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

The LCM of 351,160,310,430,620 is 74861280.

Find LCM of 351,160,310,430,620 with Prime Factorization

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

2 x 2 x 5 x 31 x 351 x 8 x 1 x 43 x 1 = 74861280

Therefore, the lowest common multiple of 351,160,310,430,620 is 74861280.

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.

351 x 160 x 310 x 430 x 620 = 4641399360000

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

310 : 1, 2, 5, 10, 31, 62, 155, 310

430 : 1, 2, 5, 10, 43, 86, 215, 430

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,160,310,430,620, is 1.

Now, the common factors can be found like this.

351:3x 3x 3x 13

160:2x 2x 2x 2x 2x 5

310:2x 5x 31

430:2x 5x 43

620:2x 2x 5x 31

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 5x 5x 5x 31 = 62000

Therefore, the value for common factors is 62000.

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 = 4641399360000/(1x62000)

LCM = 4641399360000/62000

LCM = 74861280

Thus, we can understand that the LCM of 351,160,310,430,620 is 74861280.
