Given numbers are 671,561,374,415

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

The LCM of 671,561,374,415 is 28403430.

Find LCM of 671,561,374,415 with Prime Factorization

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

11 x 17 x 61 x 3 x 2 x 415 = 28403430

Therefore, the lowest common multiple of 671,561,374,415 is 28403430.

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.

671 x 561 x 374 x 415 = 58425855510

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.

671 : 1, 11, 61, 671

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

374 : 1, 2, 11, 17, 22, 34, 187, 374

415 : 1, 5, 83, 415

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,561,374,415, is 1.

Now, the common factors can be found like this.

671:11x 61

561:3x 11x 17

374:2x 11x 17

415:5x 83

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

11x 11x 17 = 2057

Therefore, the value for common factors is 2057.

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 = 58425855510/(1x2057)

LCM = 58425855510/2057

LCM = 28403430

Thus, we can understand that the LCM of 671,561,374,415 is 28403430.
