Given numbers are 278,538,917

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

The LCM of 278,538,917 is 68575094.

Find LCM of 278,538,917 with Prime Factorization

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

2 x 139 x 269 x 917 = 68575094

Therefore, the lowest common multiple of 278,538,917 is 68575094.

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 917 = 137150188

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

917 : 1, 7, 131, 917

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,538,917, is 1.

Now, the common factors can be found like this.

278:2x 139

538:2x 269

917:7x 131

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

2 = 2

Therefore, the value for common factors is 2.

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 = 137150188/(1x2)

LCM = 137150188/2

LCM = 68575094

Thus, we can understand that the LCM of 278,538,917 is 68575094.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 959, 966, 975
