Given numbers are 156,948,420,440

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

The LCM of 156,948,420,440 is 9489480.

Find LCM of 156,948,420,440 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 79 x 7 x 22 = 9489480

Therefore, the lowest common multiple of 156,948,420,440 is 9489480.

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.

156 x 948 x 420 x 440 = 27329702400

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.

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

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,948,420,440, is 4.

Now, the common factors can be found like this.

156:2x 2x 3x 13

948:2x 2x 3x 79

420:2x 2x 3x 5x 7

440:2x 2x 2x 5x 11

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 2x 2x 3x 3x 5 = 720

Therefore, the value for common factors is 720.

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 = 27329702400/(4x720)

LCM = 27329702400/2880

LCM = 9489480

Thus, we can understand that the LCM of 156,948,420,440 is 9489480.
