Given numbers are 391,238,122,816

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

The LCM of 391,238,122,816 is 8013936.

Find LCM of 391,238,122,816 with Prime Factorization

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

2 x 17 x 23 x 7 x 61 x 24 = 8013936

Therefore, the lowest common multiple of 391,238,122,816 is 8013936.

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.

391 x 238 x 122 x 816 = 9264110016

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.

391 : 1, 17, 23, 391

238 : 1, 2, 7, 14, 17, 34, 119, 238

122 : 1, 2, 61, 122

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,238,122,816, is 1.

Now, the common factors can be found like this.

391:17x 23

238:2x 7x 17

122:2x 61

816:2x 2x 2x 2x 3x 17

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 17x 17 = 1156

Therefore, the value for common factors is 1156.

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 = 9264110016/(1x1156)

LCM = 9264110016/1156

LCM = 8013936

Thus, we can understand that the LCM of 391,238,122,816 is 8013936.
