Given numbers are 438,655,278,284

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

The LCM of 438,655,278,284 is 5662634820.

Find LCM of 438,655,278,284 with Prime Factorization

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

2 x 219 x 655 x 139 x 142 = 5662634820

Therefore, the lowest common multiple of 438,655,278,284 is 5662634820.

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 655 x 278 x 284 = 22650539280

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

655 : 1, 5, 131, 655

278 : 1, 2, 139, 278

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,655,278,284, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

655:5x 131

278:2x 139

284:2x 2x 71

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 = 22650539280/(1x4)

LCM = 22650539280/4

LCM = 5662634820

Thus, we can understand that the LCM of 438,655,278,284 is 5662634820.
