Given numbers are 823,220,472,403

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

The LCM of 823,220,472,403 is 8610127240.

Find LCM of 823,220,472,403 with Prime Factorization

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

2 x 2 x 823 x 55 x 118 x 403 = 8610127240

Therefore, the lowest common multiple of 823,220,472,403 is 8610127240.

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.

823 x 220 x 472 x 403 = 34440508960

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.

823 : 1, 823

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

472 : 1, 2, 4, 8, 59, 118, 236, 472

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,220,472,403, is 1.

Now, the common factors can be found like this.

823:823

220:2x 2x 5x 11

472:2x 2x 2x 59

403:13x 31

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 34440508960/(1x4)

LCM = 34440508960/4

LCM = 8610127240

Thus, we can understand that the LCM of 823,220,472,403 is 8610127240.
