Given numbers are 515,142,782,272

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

The LCM of 515,142,782,272 is 228750640.

Find LCM of 515,142,782,272 with Prime Factorization

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

2 x 17 x 515 x 71 x 23 x 8 = 228750640

Therefore, the lowest common multiple of 515,142,782,272 is 228750640.

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.

515 x 142 x 782 x 272 = 15555043520

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.

515 : 1, 5, 103, 515

142 : 1, 2, 71, 142

782 : 1, 2, 17, 23, 34, 46, 391, 782

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,142,782,272, is 1.

Now, the common factors can be found like this.

515:5x 103

142:2x 71

782:2x 17x 23

272:2x 2x 2x 2x 17

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 17 = 68

Therefore, the value for common factors is 68.

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 = 15555043520/(1x68)

LCM = 15555043520/68

LCM = 228750640

Thus, we can understand that the LCM of 515,142,782,272 is 228750640.
