Given numbers are 347,442,278

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

The LCM of 347,442,278 is 21318986.

Find LCM of 347,442,278 with Prime Factorization

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

2 x 347 x 221 x 139 = 21318986

Therefore, the lowest common multiple of 347,442,278 is 21318986.

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.

347 x 442 x 278 = 42637972

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.

347 : 1, 347

442 : 1, 2, 13, 17, 26, 34, 221, 442

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,442,278, is 1.

Now, the common factors can be found like this.

347:347

442:2x 13x 17

278:2x 139

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 = 42637972/(1x2)

LCM = 42637972/2

LCM = 21318986

Thus, we can understand that the LCM of 347,442,278 is 21318986.

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

• LCM of 359, 681, 494
• LCM of 344, 133, 511
