Given numbers are 721,122,483,639

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

The LCM of 721,122,483,639 is 1292777514.

Find LCM of 721,122,483,639 with Prime Factorization

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

3 x 7 x 103 x 122 x 23 x 213 = 1292777514

Therefore, the lowest common multiple of 721,122,483,639 is 1292777514.

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.

721 x 122 x 483 x 639 = 27148327794

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.

721 : 1, 7, 103, 721

122 : 1, 2, 61, 122

483 : 1, 3, 7, 21, 23, 69, 161, 483

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,122,483,639, is 1.

Now, the common factors can be found like this.

721:7x 103

122:2x 61

483:3x 7x 23

639:3x 3x 71

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 27148327794/(1x21)

LCM = 27148327794/21

LCM = 1292777514

Thus, we can understand that the LCM of 721,122,483,639 is 1292777514.
