Given numbers are 278,417,169,903

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

The LCM of 278,417,169,903 is 42424746.

Find LCM of 278,417,169,903 with Prime Factorization

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

3 x 139 x 2 x 1 x 169 x 301 = 42424746

Therefore, the lowest common multiple of 278,417,169,903 is 42424746.

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 417 x 169 x 903 = 17691119082

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

417 : 1, 3, 139, 417

169 : 1, 13, 169

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,417,169,903, is 1.

Now, the common factors can be found like this.

278:2x 139

417:3x 139

169:13x 13

903:3x 7x 43

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

3x 139 = 417

Therefore, the value for common factors is 417.

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 = 17691119082/(1x417)

LCM = 17691119082/417

LCM = 42424746

Thus, we can understand that the LCM of 278,417,169,903 is 42424746.
