Given numbers are 798,221,278,146

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

The LCM of 798,221,278,146 is 1789504626.

Find LCM of 798,221,278,146 with Prime Factorization

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

2 x 399 x 221 x 139 x 73 = 1789504626

Therefore, the lowest common multiple of 798,221,278,146 is 1789504626.

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.

798 x 221 x 278 x 146 = 7158018504

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

221 : 1, 13, 17, 221

278 : 1, 2, 139, 278

146 : 1, 2, 73, 146

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,221,278,146, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

221:13x 17

278:2x 139

146:2x 73

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 = 7158018504/(1x4)

LCM = 7158018504/4

LCM = 1789504626

Thus, we can understand that the LCM of 798,221,278,146 is 1789504626.
