Given numbers are 561,153,367,691

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

The LCM of 561,153,367,691 is 426803751.

Find LCM of 561,153,367,691 with Prime Factorization

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

3 x 17 x 11 x 3 x 367 x 691 = 426803751

Therefore, the lowest common multiple of 561,153,367,691 is 426803751.

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.

561 x 153 x 367 x 691 = 21766991301

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

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

367 : 1, 367

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,153,367,691, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

153:3x 3x 17

367:367

691:691

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

3x 17 = 51

Therefore, the value for common factors is 51.

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 = 21766991301/(1x51)

LCM = 21766991301/51

LCM = 426803751

Thus, we can understand that the LCM of 561,153,367,691 is 426803751.
