Given numbers are 231,432,321,974

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

The LCM of 231,432,321,974 is 1733353776.

Find LCM of 231,432,321,974 with Prime Factorization

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

2 x 3 x 77 x 72 x 107 x 487 = 1733353776

Therefore, the lowest common multiple of 231,432,321,974 is 1733353776.

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.

231 x 432 x 321 x 974 = 31200367968

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.

231 : 1, 3, 7, 11, 21, 33, 77, 231

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

321 : 1, 3, 107, 321

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,432,321,974, is 1.

Now, the common factors can be found like this.

231:3x 7x 11

432:2x 2x 2x 2x 3x 3x 3

321:3x 107

974:2x 487

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 31200367968/(1x18)

LCM = 31200367968/18

LCM = 1733353776

Thus, we can understand that the LCM of 231,432,321,974 is 1733353776.
