Given numbers are 921,335,412,721

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

The LCM of 921,335,412,721 is 889814940.

Find LCM of 921,335,412,721 with Prime Factorization

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

103 x 921 x 335 x 4 x 7 = 889814940

Therefore, the lowest common multiple of 921,335,412,721 is 889814940.

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.

921 x 335 x 412 x 721 = 91650938820

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.

921 : 1, 3, 307, 921

335 : 1, 5, 67, 335

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

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,335,412,721, is 1.

Now, the common factors can be found like this.

921:3x 307

335:5x 67

412:2x 2x 103

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.

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 = 91650938820/(1x103)

LCM = 91650938820/103

LCM = 889814940

Thus, we can understand that the LCM of 921,335,412,721 is 889814940.
