Given numbers are 721,223,661,993,412

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

The LCM of 721,223,661,993,412 is 422134480236.

Find LCM of 721,223,661,993,412 with Prime Factorization

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

103 x 7 x 223 x 661 x 993 x 4 = 422134480236

Therefore, the lowest common multiple of 721,223,661,993,412 is 422134480236.

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 223 x 661 x 993 x 412 = 43479851464308

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

223 : 1, 223

661 : 1, 661

993 : 1, 3, 331, 993

412 : 1, 2, 4, 103, 206, 412

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,223,661,993,412, is 1.

Now, the common factors can be found like this.

721:7x 103

223:223

661:661

993:3x 331

412:2x 2x 103

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

103 = 103

Therefore, the value for common factors is 103.

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 = 43479851464308/(1x103)

LCM = 43479851464308/103

LCM = 422134480236

Thus, we can understand that the LCM of 721,223,661,993,412 is 422134480236.
