Given numbers are 161,429,164,715

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

The LCM of 161,429,164,715 is 56636580.

Find LCM of 161,429,164,715 with Prime Factorization

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

11 x 13 x 161 x 3 x 164 x 5 = 56636580

Therefore, the lowest common multiple of 161,429,164,715 is 56636580.

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 429 x 164 x 715 = 8099030940

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

429 : 1, 3, 11, 13, 33, 39, 143, 429

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

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,429,164,715, is 1.

Now, the common factors can be found like this.

161:7x 23

429:3x 11x 13

164:2x 2x 41

715:5x 11x 13

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

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 8099030940/(1x143)

LCM = 8099030940/143

LCM = 56636580

Thus, we can understand that the LCM of 161,429,164,715 is 56636580.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 520, 203, 969, 793
