Given numbers are 788,238,138,551,278

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

The LCM of 788,238,138,551,278 is 495551355852.

Find LCM of 788,238,138,551,278 with Prime Factorization

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

2 x 394 x 119 x 69 x 551 x 139 = 495551355852

Therefore, the lowest common multiple of 788,238,138,551,278 is 495551355852.

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.

788 x 238 x 138 x 551 x 278 = 3964410846816

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.

788 : 1, 2, 4, 197, 394, 788

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

551 : 1, 19, 29, 551

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,238,138,551,278, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

238:2x 7x 17

138:2x 3x 23

551:19x 29

278:2x 139

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 2 = 8

Therefore, the value for common factors is 8.

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 = 3964410846816/(1x8)

LCM = 3964410846816/8

LCM = 495551355852

Thus, we can understand that the LCM of 788,238,138,551,278 is 495551355852.
