Given numbers are 128,580,274,931

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

The LCM of 128,580,274,931 is 2367272320.

Find LCM of 128,580,274,931 with Prime Factorization

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

2 x 2 x 32 x 145 x 137 x 931 = 2367272320

Therefore, the lowest common multiple of 128,580,274,931 is 2367272320.

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.

128 x 580 x 274 x 931 = 18938178560

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.

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

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

274 : 1, 2, 137, 274

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,580,274,931, is 1.

Now, the common factors can be found like this.

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

580:2x 2x 5x 29

274:2x 137

931:7x 7x 19

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 18938178560/(1x8)

LCM = 18938178560/8

LCM = 2367272320

Thus, we can understand that the LCM of 128,580,274,931 is 2367272320.
