Given numbers are 155,869,316,389

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

The LCM of 155,869,316,389 is 209585420.

Find LCM of 155,869,316,389 with Prime Factorization

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

79 x 155 x 11 x 4 x 389 = 209585420

Therefore, the lowest common multiple of 155,869,316,389 is 209585420.

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.

155 x 869 x 316 x 389 = 16557248180

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.

155 : 1, 5, 31, 155

869 : 1, 11, 79, 869

316 : 1, 2, 4, 79, 158, 316

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,869,316,389, is 1.

Now, the common factors can be found like this.

155:5x 31

869:11x 79

316:2x 2x 79

389:389

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

79 = 79

Therefore, the value for common factors is 79.

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 = 16557248180/(1x79)

LCM = 16557248180/79

LCM = 209585420

Thus, we can understand that the LCM of 155,869,316,389 is 209585420.
