Given numbers are 287,138,664,287,346

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

The LCM of 287,138,664,287,346 is 2274810216.

Find LCM of 287,138,664,287,346 with Prime Factorization

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

2 x 7 x 41 x 1 x 69 x 332 x 1 x 173 = 2274810216

Therefore, the lowest common multiple of 287,138,664,287,346 is 2274810216.

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.

287 x 138 x 664 x 287 x 346 = 2611482127968

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.

287 : 1, 7, 41, 287

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

664 : 1, 2, 4, 8, 83, 166, 332, 664

287 : 1, 7, 41, 287

346 : 1, 2, 173, 346

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,138,664,287,346, is 1.

Now, the common factors can be found like this.

287:7x 41

138:2x 3x 23

664:2x 2x 2x 83

287:7x 41

346:2x 173

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 7x 41 = 1148

Therefore, the value for common factors is 1148.

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 = 2611482127968/(1x1148)

LCM = 2611482127968/1148

LCM = 2274810216

Thus, we can understand that the LCM of 287,138,664,287,346 is 2274810216.
