Given numbers are 161,515,644,169

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

The LCM of 161,515,644,169 is 56050540.

Find LCM of 161,515,644,169 with Prime Factorization

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

7 x 23 x 1 x 515 x 4 x 169 = 56050540

Therefore, the lowest common multiple of 161,515,644,169 is 56050540.

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 515 x 644 x 169 = 9024136940

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

515 : 1, 5, 103, 515

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,515,644,169, is 1.

Now, the common factors can be found like this.

161:7x 23

515:5x 103

644:2x 2x 7x 23

169:13x 13

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 9024136940/(1x161)

LCM = 9024136940/161

LCM = 56050540

Thus, we can understand that the LCM of 161,515,644,169 is 56050540.
