Given numbers are 278,538,420,886

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

The LCM of 278,538,420,886 is 6956969460.

Find LCM of 278,538,420,886 with Prime Factorization

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

2 x 139 x 269 x 210 x 443 = 6956969460

Therefore, the lowest common multiple of 278,538,420,886 is 6956969460.

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 538 x 420 x 886 = 55655755680

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

538 : 1, 2, 269, 538

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

886 : 1, 2, 443, 886

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,538,420,886, is 2.

Now, the common factors can be found like this.

278:2x 139

538:2x 269

420:2x 2x 3x 5x 7

886:2x 443

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 = 55655755680/(2x4)

LCM = 55655755680/8

LCM = 6956969460

Thus, we can understand that the LCM of 278,538,420,886 is 6956969460.
