Given numbers are 438,817,787,686

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

The LCM of 438,817,787,686 is 96597307086.

Find LCM of 438,817,787,686 with Prime Factorization

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

2 x 219 x 817 x 787 x 343 = 96597307086

Therefore, the lowest common multiple of 438,817,787,686 is 96597307086.

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.

438 x 817 x 787 x 686 = 193194614172

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

817 : 1, 19, 43, 817

787 : 1, 787

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,817,787,686, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

817:19x 43

787:787

686:2x 7x 7x 7

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 = 193194614172/(1x2)

LCM = 193194614172/2

LCM = 96597307086

Thus, we can understand that the LCM of 438,817,787,686 is 96597307086.
