Given numbers are 278,242,218,650

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

The LCM of 278,242,218,650 is 1191626150.

Find LCM of 278,242,218,650 with Prime Factorization

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

2 x 139 x 121 x 109 x 325 = 1191626150

Therefore, the lowest common multiple of 278,242,218,650 is 1191626150.

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.

278 x 242 x 218 x 650 = 9533009200

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.

278 : 1, 2, 139, 278

242 : 1, 2, 11, 22, 121, 242

218 : 1, 2, 109, 218

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,242,218,650, is 2.

Now, the common factors can be found like this.

278:2x 139

242:2x 11x 11

218:2x 109

650:2x 5x 5x 13

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 = 9533009200/(2x4)

LCM = 9533009200/8

LCM = 1191626150

Thus, we can understand that the LCM of 278,242,218,650 is 1191626150.
