Given numbers are 310,610,515,278,785

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

The LCM of 310,610,515,278,785 is 42505311790.

Find LCM of 310,610,515,278,785 with Prime Factorization

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

2 x 5 x 31 x 61 x 103 x 139 x 157 = 42505311790

Therefore, the lowest common multiple of 310,610,515,278,785 is 42505311790.

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.

310 x 610 x 515 x 278 x 785 = 21252655895000

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.

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

610 : 1, 2, 5, 10, 61, 122, 305, 610

515 : 1, 5, 103, 515

278 : 1, 2, 139, 278

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,610,515,278,785, is 1.

Now, the common factors can be found like this.

310:2x 5x 31

610:2x 5x 61

515:5x 103

278:2x 139

785:5x 157

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 5x 5x 5 = 500

Therefore, the value for common factors is 500.

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 = 21252655895000/(1x500)

LCM = 21252655895000/500

LCM = 42505311790

Thus, we can understand that the LCM of 310,610,515,278,785 is 42505311790.
