Given numbers are 456,438,998,221,346

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

The LCM of 456,438,998,221,346 is 635077351896.

Find LCM of 456,438,998,221,346 with Prime Factorization

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

2 x 3 x 76 x 73 x 499 x 221 x 173 = 635077351896

Therefore, the lowest common multiple of 456,438,998,221,346 is 635077351896.

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.

456 x 438 x 998 x 221 x 346 = 15241856445504

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.

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

438 : 1, 2, 3, 6, 73, 146, 219, 438

998 : 1, 2, 499, 998

221 : 1, 13, 17, 221

346 : 1, 2, 173, 346

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,438,998,221,346, is 1.

Now, the common factors can be found like this.

456:2x 2x 2x 3x 19

438:2x 3x 73

998:2x 499

221:13x 17

346:2x 173

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 15241856445504/(1x24)

LCM = 15241856445504/24

LCM = 635077351896

Thus, we can understand that the LCM of 456,438,998,221,346 is 635077351896.
