Given numbers are 721,312,155,758

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

The LCM of 721,312,155,758 is 13214805240.

Find LCM of 721,312,155,758 with Prime Factorization

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

2 x 721 x 156 x 155 x 379 = 13214805240

Therefore, the lowest common multiple of 721,312,155,758 is 13214805240.

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.

721 x 312 x 155 x 758 = 26429610480

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.

721 : 1, 7, 103, 721

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

155 : 1, 5, 31, 155

758 : 1, 2, 379, 758

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,312,155,758, is 1.

Now, the common factors can be found like this.

721:7x 103

312:2x 2x 2x 3x 13

155:5x 31

758:2x 379

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 = 26429610480/(1x2)

LCM = 26429610480/2

LCM = 13214805240

Thus, we can understand that the LCM of 721,312,155,758 is 13214805240.
