Given numbers are 821,786,186,699

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

The LCM of 821,786,186,699 is 4661045238.

Find LCM of 821,786,186,699 with Prime Factorization

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

2 x 3 x 821 x 131 x 31 x 233 = 4661045238

Therefore, the lowest common multiple of 821,786,186,699 is 4661045238.

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.

821 x 786 x 186 x 699 = 83898814284

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.

821 : 1, 821

786 : 1, 2, 3, 6, 131, 262, 393, 786

186 : 1, 2, 3, 6, 31, 62, 93, 186

699 : 1, 3, 233, 699

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,786,186,699, is 1.

Now, the common factors can be found like this.

821:821

786:2x 3x 131

186:2x 3x 31

699:3x 233

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 83898814284/(1x18)

LCM = 83898814284/18

LCM = 4661045238

Thus, we can understand that the LCM of 821,786,186,699 is 4661045238.
