Given numbers are 455,221,791,234

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

The LCM of 455,221,791,234 is 15732990.

Find LCM of 455,221,791,234 with Prime Factorization

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

7 x 13 x 5 x 17 x 113 x 18 = 15732990

Therefore, the lowest common multiple of 455,221,791,234 is 15732990.

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.

455 x 221 x 791 x 234 = 18612127170

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

221 : 1, 13, 17, 221

791 : 1, 7, 113, 791

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,221,791,234, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

221:13x 17

791:7x 113

234:2x 3x 3x 13

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

7x 13x 13 = 1183

Therefore, the value for common factors is 1183.

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 = 18612127170/(1x1183)

LCM = 18612127170/1183

LCM = 15732990

Thus, we can understand that the LCM of 455,221,791,234 is 15732990.
