Given numbers are 161,568,676,670

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

The LCM of 161,568,676,670 is 5177328520.

Find LCM of 161,568,676,670 with Prime Factorization

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

2 x 2 x 161 x 142 x 169 x 335 = 5177328520

Therefore, the lowest common multiple of 161,568,676,670 is 5177328520.

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.

161 x 568 x 676 x 670 = 41418628160

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.

161 : 1, 7, 23, 161

568 : 1, 2, 4, 8, 71, 142, 284, 568

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,568,676,670, is 1.

Now, the common factors can be found like this.

161:7x 23

568:2x 2x 2x 71

676:2x 2x 13x 13

670:2x 5x 67

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 2 = 8

Therefore, the value for common factors is 8.

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 = 41418628160/(1x8)

LCM = 41418628160/8

LCM = 5177328520

Thus, we can understand that the LCM of 161,568,676,670 is 5177328520.
