Given numbers are 645,229,871,916

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

The LCM of 645,229,871,916 is 514604220.

Find LCM of 645,229,871,916 with Prime Factorization

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

229 x 645 x 1 x 871 x 4 = 514604220

Therefore, the lowest common multiple of 645,229,871,916 is 514604220.

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.

645 x 229 x 871 x 916 = 117844366380

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

229 : 1, 229

871 : 1, 13, 67, 871

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 645,229,871,916, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

229:229

871:13x 67

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.

229 = 229

Therefore, the value for common factors is 229.

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 = 117844366380/(1x229)

LCM = 117844366380/229

LCM = 514604220

Thus, we can understand that the LCM of 645,229,871,916 is 514604220.
