The LCM of 387,553,418,429 is 1162935774.

Find LCM of 387,553,418,429 with Prime Factorization


3 387, 553, 418, 429
11 129, 553, 418, 143
129, 553, 38, 13

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

3 x 11 x 129 x 553 x 38 x 13 = 1162935774

Therefore, the lowest common multiple of 387,553,418,429 is 1162935774.

LCM Formula to Find Lowest Common Multiple of 387,553,418,429

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.

387 x 553 x 418 x 429 = 38376880542

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.

387 : 1, 3, 9, 43, 129, 387

553 : 1, 7, 79, 553

418 : 1, 2, 11, 19, 22, 38, 209, 418

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,553,418,429, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

553:7x 79

418:2x 11x 19

429:3x 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.

3x 11 = 33

Therefore, the value for common factors is 33.

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 = 38376880542/(1x33)

LCM = 38376880542/33

LCM = 1162935774

Thus, we can understand that the LCM of 387,553,418,429 is 1162935774.
