Given numbers are 340,974,296,421

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

The LCM of 340,974,296,421 is 5158479320.

Find LCM of 340,974,296,421 with Prime Factorization

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

2 x 2 x 85 x 487 x 74 x 421 = 5158479320

Therefore, the lowest common multiple of 340,974,296,421 is 5158479320.

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.

340 x 974 x 296 x 421 = 41267834560

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.

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

974 : 1, 2, 487, 974

296 : 1, 2, 4, 8, 37, 74, 148, 296

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,974,296,421, is 1.

Now, the common factors can be found like this.

340:2x 2x 5x 17

974:2x 487

296:2x 2x 2x 37

421:421

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 2 = 8

Therefore, the value for common factors is 8.

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 = 41267834560/(1x8)

LCM = 41267834560/8

LCM = 5158479320

Thus, we can understand that the LCM of 340,974,296,421 is 5158479320.
