Given numbers are 431,168,697,286

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

The LCM of 431,168,697,286 is 7216977768.

Find LCM of 431,168,697,286 with Prime Factorization

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

2 x 431 x 84 x 697 x 143 = 7216977768

Therefore, the lowest common multiple of 431,168,697,286 is 7216977768.

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.

431 x 168 x 697 x 286 = 14433955536

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.

431 : 1, 431

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

697 : 1, 17, 41, 697

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,168,697,286, is 1.

Now, the common factors can be found like this.

431:431

168:2x 2x 2x 3x 7

697:17x 41

286:2x 11x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 14433955536/(1x2)

LCM = 14433955536/2

LCM = 7216977768

Thus, we can understand that the LCM of 431,168,697,286 is 7216977768.
