Given numbers are 278,393,787,139

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

The LCM of 278,393,787,139 is 85982898.

Find LCM of 278,393,787,139 with Prime Factorization

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

139 x 2 x 393 x 787 x 1 = 85982898

Therefore, the lowest common multiple of 278,393,787,139 is 85982898.

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 393 x 787 x 139 = 11951622822

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

393 : 1, 3, 131, 393

787 : 1, 787

139 : 1, 139

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,393,787,139, is 1.

Now, the common factors can be found like this.

278:2x 139

393:3x 131

787:787

139:139

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

139 = 139

Therefore, the value for common factors is 139.

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 = 11951622822/(1x139)

LCM = 11951622822/139

LCM = 85982898

Thus, we can understand that the LCM of 278,393,787,139 is 85982898.
