Given numbers are 618,615,629,721

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

The LCM of 618,615,629,721 is 557816070.

Find LCM of 618,615,629,721 with Prime Factorization

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

3 x 103 x 2 x 205 x 629 x 7 = 557816070

Therefore, the lowest common multiple of 618,615,629,721 is 557816070.

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.

618 x 615 x 629 x 721 = 172365165630

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

615 : 1, 3, 5, 15, 41, 123, 205, 615

629 : 1, 17, 37, 629

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,615,629,721, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

615:3x 5x 41

629:17x 37

721:7x 103

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

3x 103 = 309

Therefore, the value for common factors is 309.

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 = 172365165630/(1x309)

LCM = 172365165630/309

LCM = 557816070

Thus, we can understand that the LCM of 618,615,629,721 is 557816070.
