Given numbers are 438,699,403,963

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

The LCM of 438,699,403,963 is 13202011602.

Find LCM of 438,699,403,963 with Prime Factorization

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

3 x 146 x 233 x 403 x 321 = 13202011602

Therefore, the lowest common multiple of 438,699,403,963 is 13202011602.

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 699 x 403 x 963 = 118818104418

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

699 : 1, 3, 233, 699

403 : 1, 13, 31, 403

963 : 1, 3, 9, 107, 321, 963

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,699,403,963, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

699:3x 233

403:13x 31

963:3x 3x 107

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 118818104418/(1x9)

LCM = 118818104418/9

LCM = 13202011602

Thus, we can understand that the LCM of 438,699,403,963 is 13202011602.
