Given numbers are 153,493,357,661

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

The LCM of 153,493,357,661 is 20529999.

Find LCM of 153,493,357,661 with Prime Factorization

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

3 x 17 x 3 x 29 x 7 x 661 = 20529999

Therefore, the lowest common multiple of 153,493,357,661 is 20529999.

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.

153 x 493 x 357 x 661 = 17799509133

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.

153 : 1, 3, 9, 17, 51, 153

493 : 1, 17, 29, 493

357 : 1, 3, 7, 17, 21, 51, 119, 357

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,493,357,661, is 1.

Now, the common factors can be found like this.

153:3x 3x 17

493:17x 29

357:3x 7x 17

661:661

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

3x 17x 17 = 867

Therefore, the value for common factors is 867.

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 = 17799509133/(1x867)

LCM = 17799509133/867

LCM = 20529999

Thus, we can understand that the LCM of 153,493,357,661 is 20529999.
