Given numbers are 403,345,217,916

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

The LCM of 403,345,217,916 is 891492420.

Find LCM of 403,345,217,916 with Prime Factorization

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

31 x 13 x 345 x 7 x 916 = 891492420

Therefore, the lowest common multiple of 403,345,217,916 is 891492420.

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.

403 x 345 x 217 x 916 = 27636265020

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.

403 : 1, 13, 31, 403

345 : 1, 3, 5, 15, 23, 69, 115, 345

217 : 1, 7, 31, 217

916 : 1, 2, 4, 229, 458, 916

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,345,217,916, is 1.

Now, the common factors can be found like this.

403:13x 31

345:3x 5x 23

217:7x 31

916:2x 2x 229

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

31 = 31

Therefore, the value for common factors is 31.

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 = 27636265020/(1x31)

LCM = 27636265020/31

LCM = 891492420

Thus, we can understand that the LCM of 403,345,217,916 is 891492420.
