Given numbers are 872,582,139,420

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

The LCM of 872,582,139,420 is 1234503480.

Find LCM of 872,582,139,420 with Prime Factorization

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

2 x 2 x 3 x 218 x 97 x 139 x 35 = 1234503480

Therefore, the lowest common multiple of 872,582,139,420 is 1234503480.

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.

872 x 582 x 139 x 420 = 29628083520

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

582 : 1, 2, 3, 6, 97, 194, 291, 582

139 : 1, 139

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,582,139,420, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

582:2x 3x 97

139:139

420:2x 2x 3x 5x 7

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 29628083520/(1x24)

LCM = 29628083520/24

LCM = 1234503480

Thus, we can understand that the LCM of 872,582,139,420 is 1234503480.
