Calculate the LCM of 470,685,821,681,237

Given numbers are 470,685,821,681,237

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

The LCM of 470,685,821,681,237 is 2844040557810.

Find LCM of 470,685,821,681,237 with Prime Factorization


3 470, 685, 821, 681, 237
5 470, 685, 821, 227, 79
94, 137, 821, 227, 79

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

3 x 5 x 94 x 137 x 821 x 227 x 79 = 2844040557810

Therefore, the lowest common multiple of 470,685,821,681,237 is 2844040557810.

LCM Formula to Find Lowest Common Multiple of 470,685,821,681,237

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.

470 x 685 x 821 x 681 x 237 = 42660608367150

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.

470 : 1, 2, 5, 10, 47, 94, 235, 470

685 : 1, 5, 137, 685

821 : 1, 821

681 : 1, 3, 227, 681

237 : 1, 3, 79, 237

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,685,821,681,237, is 1.

Now, the common factors can be found like this.

470:2x 5x 47

685:5x 137

821:821

681:3x 227

237:3x 79

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 42660608367150/(1x15)

LCM = 42660608367150/15

LCM = 2844040557810

Thus, we can understand that the LCM of 470,685,821,681,237 is 2844040557810.
