Given numbers are 671,158,689,340

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

The LCM of 671,158,689,340 is 12417888340.

Find LCM of 671,158,689,340 with Prime Factorization

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

2 x 671 x 79 x 689 x 170 = 12417888340

Therefore, the lowest common multiple of 671,158,689,340 is 12417888340.

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 158 x 689 x 340 = 24835776680

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

158 : 1, 2, 79, 158

689 : 1, 13, 53, 689

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,158,689,340, is 1.

Now, the common factors can be found like this.

671:11x 61

158:2x 79

689:13x 53

340:2x 2x 5x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 24835776680/(1x2)

LCM = 24835776680/2

LCM = 12417888340

Thus, we can understand that the LCM of 671,158,689,340 is 12417888340.
