Given numbers are 428,368,697,487,396

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

The LCM of 428,368,697,487,396 is 1323209256336.

Find LCM of 428,368,697,487,396 with Prime Factorization

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

2 x 2 x 107 x 92 x 697 x 487 x 99 = 1323209256336

Therefore, the lowest common multiple of 428,368,697,487,396 is 1323209256336.

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.

428 x 368 x 697 x 487 x 396 = 21171348101376

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.

428 : 1, 2, 4, 107, 214, 428

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

697 : 1, 17, 41, 697

487 : 1, 487

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,368,697,487,396, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

368:2x 2x 2x 2x 23

697:17x 41

487:487

396:2x 2x 3x 3x 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 2 = 16

Therefore, the value for common factors is 16.

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 = 21171348101376/(1x16)

LCM = 21171348101376/16

LCM = 1323209256336

Thus, we can understand that the LCM of 428,368,697,487,396 is 1323209256336.
