Given numbers are 667,415,676,473,420

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

The LCM of 667,415,676,473,420 is 1858664747940.

Find LCM of 667,415,676,473,420 with Prime Factorization

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

2 x 2 x 5 x 667 x 83 x 169 x 473 x 21 = 1858664747940

Therefore, the lowest common multiple of 667,415,676,473,420 is 1858664747940.

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.

667 x 415 x 676 x 473 x 420 = 37173294958800

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.

667 : 1, 23, 29, 667

415 : 1, 5, 83, 415

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

473 : 1, 11, 43, 473

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,415,676,473,420, is 1.

Now, the common factors can be found like this.

667:23x 29

415:5x 83

676:2x 2x 13x 13

473:11x 43

420:2x 2x 3x 5x 7

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 37173294958800/(1x20)

LCM = 37173294958800/20

LCM = 1858664747940

Thus, we can understand that the LCM of 667,415,676,473,420 is 1858664747940.
