Given numbers are 877,221,357,221

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

The LCM of 877,221,357,221 is 4070157.

Find LCM of 877,221,357,221 with Prime Factorization

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

13 x 17 x 877 x 1 x 21 x 1 = 4070157

Therefore, the lowest common multiple of 877,221,357,221 is 4070157.

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.

877 x 221 x 357 x 221 = 15291579849

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.

877 : 1, 877

221 : 1, 13, 17, 221

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

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 877,221,357,221, is 1.

Now, the common factors can be found like this.

877:877

221:13x 17

357:3x 7x 17

221:13x 17

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

13x 17x 17 = 3757

Therefore, the value for common factors is 3757.

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 = 15291579849/(1x3757)

LCM = 15291579849/3757

LCM = 4070157

Thus, we can understand that the LCM of 877,221,357,221 is 4070157.
