Given numbers are 690,227,215,862

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

The LCM of 690,227,215,862 is 2902823790.

Find LCM of 690,227,215,862 with Prime Factorization

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

2 x 5 x 69 x 227 x 43 x 431 = 2902823790

Therefore, the lowest common multiple of 690,227,215,862 is 2902823790.

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.

690 x 227 x 215 x 862 = 29028237900

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

227 : 1, 227

215 : 1, 5, 43, 215

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,227,215,862, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

227:227

215:5x 43

862:2x 431

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 29028237900/(1x10)

LCM = 29028237900/10

LCM = 2902823790

Thus, we can understand that the LCM of 690,227,215,862 is 2902823790.
