Given numbers are 426,254,860,869

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

The LCM of 426,254,860,869 is 20216294340.

Find LCM of 426,254,860,869 with Prime Factorization

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

2 x 213 x 127 x 430 x 869 = 20216294340

Therefore, the lowest common multiple of 426,254,860,869 is 20216294340.

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.

426 x 254 x 860 x 869 = 80865177360

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

254 : 1, 2, 127, 254

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

869 : 1, 11, 79, 869

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,254,860,869, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

254:2x 127

860:2x 2x 5x 43

869:11x 79

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 = 80865177360/(1x4)

LCM = 80865177360/4

LCM = 20216294340

Thus, we can understand that the LCM of 426,254,860,869 is 20216294340.
