Given numbers are 774,218,358,145

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

The LCM of 774,218,358,145 is 2189719530.

Find LCM of 774,218,358,145 with Prime Factorization

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

2 x 387 x 109 x 179 x 145 = 2189719530

Therefore, the lowest common multiple of 774,218,358,145 is 2189719530.

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.

774 x 218 x 358 x 145 = 8758878120

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

218 : 1, 2, 109, 218

358 : 1, 2, 179, 358

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,218,358,145, is 1.

Now, the common factors can be found like this.

774:2x 3x 3x 43

218:2x 109

358:2x 179

145:5x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 8758878120/(1x4)

LCM = 8758878120/4

LCM = 2189719530

Thus, we can understand that the LCM of 774,218,358,145 is 2189719530.
