Given numbers are 946,247,380,691

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

The LCM of 946,247,380,691 is 1614604420.

Find LCM of 946,247,380,691 with Prime Factorization

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

2 x 19 x 473 x 13 x 10 x 691 = 1614604420

Therefore, the lowest common multiple of 946,247,380,691 is 1614604420.

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.

946 x 247 x 380 x 691 = 61354967960

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.

946 : 1, 2, 11, 22, 43, 86, 473, 946

247 : 1, 13, 19, 247

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,247,380,691, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

247:13x 19

380:2x 2x 5x 19

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.

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 61354967960/(1x38)

LCM = 61354967960/38

LCM = 1614604420

Thus, we can understand that the LCM of 946,247,380,691 is 1614604420.
