Given numbers are 860,428,149,343

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

The LCM of 860,428,149,343 is 4702866140.

Find LCM of 860,428,149,343 with Prime Factorization

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

2 x 2 x 215 x 107 x 149 x 343 = 4702866140

Therefore, the lowest common multiple of 860,428,149,343 is 4702866140.

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.

860 x 428 x 149 x 343 = 18811464560

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.

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

428 : 1, 2, 4, 107, 214, 428

149 : 1, 149

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,428,149,343, is 1.

Now, the common factors can be found like this.

860:2x 2x 5x 43

428:2x 2x 107

149:149

343:7x 7x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 18811464560/(1x4)

LCM = 18811464560/4

LCM = 4702866140

Thus, we can understand that the LCM of 860,428,149,343 is 4702866140.
