Given numbers are 155,728,828,472,376

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

The LCM of 155,728,828,472,376 is 64771401240.

Find LCM of 155,728,828,472,376 with Prime Factorization

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

2 x 2 x 2 x 155 x 91 x 207 x 59 x 47 = 64771401240

Therefore, the lowest common multiple of 155,728,828,472,376 is 64771401240.

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.

155 x 728 x 828 x 472 x 376 = 16581478717440

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.

155 : 1, 5, 31, 155

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

472 : 1, 2, 4, 8, 59, 118, 236, 472

376 : 1, 2, 4, 8, 47, 94, 188, 376

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,728,828,472,376, is 1.

Now, the common factors can be found like this.

155:5x 31

728:2x 2x 2x 7x 13

828:2x 2x 3x 3x 23

472:2x 2x 2x 59

376:2x 2x 2x 47

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 2x 2x 2x 2 = 256

Therefore, the value for common factors is 256.

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 = 16581478717440/(1x256)

LCM = 16581478717440/256

LCM = 64771401240

Thus, we can understand that the LCM of 155,728,828,472,376 is 64771401240.
