Given numbers are 239,156,821,490

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

The LCM of 239,156,821,490 is 7499490180.

Find LCM of 239,156,821,490 with Prime Factorization

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

2 x 239 x 78 x 821 x 245 = 7499490180

Therefore, the lowest common multiple of 239,156,821,490 is 7499490180.

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.

239 x 156 x 821 x 490 = 14998980360

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.

239 : 1, 239

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

821 : 1, 821

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 239,156,821,490, is 1.

Now, the common factors can be found like this.

239:239

156:2x 2x 3x 13

821:821

490:2x 5x 7x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 14998980360/(1x2)

LCM = 14998980360/2

LCM = 7499490180

Thus, we can understand that the LCM of 239,156,821,490 is 7499490180.
