Given numbers are 278,802,740,455

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

The LCM of 278,802,740,455 is 3753464260.

Find LCM of 278,802,740,455 with Prime Factorization

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

2 x 5 x 139 x 401 x 74 x 91 = 3753464260

Therefore, the lowest common multiple of 278,802,740,455 is 3753464260.

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 802 x 740 x 455 = 75069285200

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

802 : 1, 2, 401, 802

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,802,740,455, is 1.

Now, the common factors can be found like this.

278:2x 139

802:2x 401

740:2x 2x 5x 37

455:5x 7x 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 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 75069285200/(1x20)

LCM = 75069285200/20

LCM = 3753464260

Thus, we can understand that the LCM of 278,802,740,455 is 3753464260.
