Given numbers are 670,946,428,164,161

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

The LCM of 670,946,428,164,161 is 447671502740.

Find LCM of 670,946,428,164,161 with Prime Factorization

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

2 x 2 x 335 x 473 x 107 x 41 x 161 = 447671502740

Therefore, the lowest common multiple of 670,946,428,164,161 is 447671502740.

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.

670 x 946 x 428 x 164 x 161 = 7162744043840

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.

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

946 : 1, 2, 11, 22, 43, 86, 473, 946

428 : 1, 2, 4, 107, 214, 428

164 : 1, 2, 4, 41, 82, 164

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,946,428,164,161, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

946:2x 11x 43

428:2x 2x 107

164:2x 2x 41

161:7x 23

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 7162744043840/(1x16)

LCM = 7162744043840/16

LCM = 447671502740

Thus, we can understand that the LCM of 670,946,428,164,161 is 447671502740.
