Given numbers are 387,624,156,69

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

The LCM of 387,624,156,69 is 1851408.

Find LCM of 387,624,156,69 with Prime Factorization

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

2 x 2 x 3 x 13 x 129 x 4 x 1 x 23 = 1851408

Therefore, the lowest common multiple of 387,624,156,69 is 1851408.

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 624 x 156 x 69 = 2599376832

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

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

69 : 1, 3, 23, 69

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,624,156,69, is 3.

Now, the common factors can be found like this.

387:3x 3x 43

624:2x 2x 2x 2x 3x 13

156:2x 2x 3x 13

69:3x 23

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

2x 2x 3x 3x 13 = 468

Therefore, the value for common factors is 468.

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 = 2599376832/(3x468)

LCM = 2599376832/1404

LCM = 1851408

Thus, we can understand that the LCM of 387,624,156,69 is 1851408.
