Given numbers are 725,307,791,921

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

The LCM of 725,307,791,921 is 528170475.

Find LCM of 725,307,791,921 with Prime Factorization

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

307 x 725 x 1 x 791 x 3 = 528170475

Therefore, the lowest common multiple of 725,307,791,921 is 528170475.

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.

725 x 307 x 791 x 921 = 162148335825

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.

725 : 1, 5, 25, 29, 145, 725

307 : 1, 307

791 : 1, 7, 113, 791

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,307,791,921, is 1.

Now, the common factors can be found like this.

725:5x 5x 29

307:307

791:7x 113

921:3x 307

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

307 = 307

Therefore, the value for common factors is 307.

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 = 162148335825/(1x307)

LCM = 162148335825/307

LCM = 528170475

Thus, we can understand that the LCM of 725,307,791,921 is 528170475.
