Given numbers are 396,620,251,224

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

The LCM of 396,620,251,224 is 862757280.

Find LCM of 396,620,251,224 with Prime Factorization

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

2 x 2 x 99 x 155 x 251 x 56 = 862757280

Therefore, the lowest common multiple of 396,620,251,224 is 862757280.

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.

396 x 620 x 251 x 224 = 13804116480

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.

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

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

251 : 1, 251

224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,620,251,224, is 1.

Now, the common factors can be found like this.

396:2x 2x 3x 3x 11

620:2x 2x 5x 31

251:251

224:2x 2x 2x 2x 2x 7

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 = 13804116480/(1x16)

LCM = 13804116480/16

LCM = 862757280

Thus, we can understand that the LCM of 396,620,251,224 is 862757280.
