Given numbers are 278,430,946,391

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

The LCM of 278,430,946,391 is 257070770.

Find LCM of 278,430,946,391 with Prime Factorization

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

2 x 43 x 139 x 5 x 11 x 391 = 257070770

Therefore, the lowest common multiple of 278,430,946,391 is 257070770.

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 430 x 946 x 391 = 44216172440

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

430 : 1, 2, 5, 10, 43, 86, 215, 430

946 : 1, 2, 11, 22, 43, 86, 473, 946

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,430,946,391, is 1.

Now, the common factors can be found like this.

278:2x 139

430:2x 5x 43

946:2x 11x 43

391:17x 23

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 43 = 172

Therefore, the value for common factors is 172.

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 = 44216172440/(1x172)

LCM = 44216172440/172

LCM = 257070770

Thus, we can understand that the LCM of 278,430,946,391 is 257070770.
