Given numbers are 638,146,898,178

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

The LCM of 638,146,898,178 is 1861143614.

Find LCM of 638,146,898,178 with Prime Factorization

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

2 x 319 x 73 x 449 x 89 = 1861143614

Therefore, the lowest common multiple of 638,146,898,178 is 1861143614.

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.

638 x 146 x 898 x 178 = 14889148912

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

146 : 1, 2, 73, 146

898 : 1, 2, 449, 898

178 : 1, 2, 89, 178

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,146,898,178, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

146:2x 73

898:2x 449

178:2x 89

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 14889148912/(2x4)

LCM = 14889148912/8

LCM = 1861143614

Thus, we can understand that the LCM of 638,146,898,178 is 1861143614.
