Given numbers are 2,537,128,921

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

The LCM of 2,537,128,921 is 21101952.

Find LCM of 2,537,128,921 with Prime Factorization

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

2 x 3 x 1 x 179 x 64 x 307 = 21101952

Therefore, the lowest common multiple of 2,537,128,921 is 21101952.

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.

2 x 537 x 128 x 921 = 126611712

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.

2 : 1, 2

537 : 1, 3, 179, 537

128 : 1, 2, 4, 8, 16, 32, 64, 128

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,537,128,921, is 1.

Now, the common factors can be found like this.

2:2

537:3x 179

128:2x 2x 2x 2x 2x 2x 2

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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 126611712/(1x6)

LCM = 126611712/6

LCM = 21101952

Thus, we can understand that the LCM of 2,537,128,921 is 21101952.
