Given numbers are 622,304,721,515

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

The LCM of 622,304,721,515 is 340831120.

Find LCM of 622,304,721,515 with Prime Factorization

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

2 x 103 x 311 x 152 x 7 x 5 = 340831120

Therefore, the lowest common multiple of 622,304,721,515 is 340831120.

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.

622 x 304 x 721 x 515 = 70211210720

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.

622 : 1, 2, 311, 622

304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304

721 : 1, 7, 103, 721

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,304,721,515, is 1.

Now, the common factors can be found like this.

622:2x 311

304:2x 2x 2x 2x 19

721:7x 103

515:5x 103

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

2x 103 = 206

Therefore, the value for common factors is 206.

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 = 70211210720/(1x206)

LCM = 70211210720/206

LCM = 340831120

Thus, we can understand that the LCM of 622,304,721,515 is 340831120.
