Given numbers are 689,238,130,454

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

The LCM of 689,238,130,454 is 186119570.

Find LCM of 689,238,130,454 with Prime Factorization

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

2 x 13 x 53 x 119 x 5 x 227 = 186119570

Therefore, the lowest common multiple of 689,238,130,454 is 186119570.

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.

689 x 238 x 130 x 454 = 9678217640

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.

689 : 1, 13, 53, 689

238 : 1, 2, 7, 14, 17, 34, 119, 238

130 : 1, 2, 5, 10, 13, 26, 65, 130

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,238,130,454, is 1.

Now, the common factors can be found like this.

689:13x 53

238:2x 7x 17

130:2x 5x 13

454:2x 227

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

2x 2x 13 = 52

Therefore, the value for common factors is 52.

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 = 9678217640/(1x52)

LCM = 9678217640/52

LCM = 186119570

Thus, we can understand that the LCM of 689,238,130,454 is 186119570.
