Given numbers are 438,556,776,215

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

The LCM of 438,556,776,215 is 5078776440.

Find LCM of 438,556,776,215 with Prime Factorization

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

2 x 2 x 219 x 139 x 194 x 215 = 5078776440

Therefore, the lowest common multiple of 438,556,776,215 is 5078776440.

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 556 x 776 x 215 = 40630211520

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

556 : 1, 2, 4, 139, 278, 556

776 : 1, 2, 4, 8, 97, 194, 388, 776

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,556,776,215, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

556:2x 2x 139

776:2x 2x 2x 97

215:5x 43

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 40630211520/(1x8)

LCM = 40630211520/8

LCM = 5078776440

Thus, we can understand that the LCM of 438,556,776,215 is 5078776440.
