Given numbers are 378,663,839,161,553

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

The LCM of 378,663,839,161,553 is 127350590094.

Find LCM of 378,663,839,161,553 with Prime Factorization

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

3 x 7 x 18 x 221 x 839 x 23 x 79 = 127350590094

Therefore, the lowest common multiple of 378,663,839,161,553 is 127350590094.

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.

378 x 663 x 839 x 161 x 553 = 18720536743818

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.

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

663 : 1, 3, 13, 17, 39, 51, 221, 663

839 : 1, 839

161 : 1, 7, 23, 161

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,663,839,161,553, is 1.

Now, the common factors can be found like this.

378:2x 3x 3x 3x 7

663:3x 13x 17

839:839

161:7x 23

553:7x 79

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

3x 7x 7 = 147

Therefore, the value for common factors is 147.

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 = 18720536743818/(1x147)

LCM = 18720536743818/147

LCM = 127350590094

Thus, we can understand that the LCM of 378,663,839,161,553 is 127350590094.
