Given numbers are 676,721,953,169

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

The LCM of 676,721,953,169 is 464488388.

Find LCM of 676,721,953,169 with Prime Factorization

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

13 x 13 x 4 x 721 x 953 x 1 = 464488388

Therefore, the lowest common multiple of 676,721,953,169 is 464488388.

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.

676 x 721 x 953 x 169 = 78498537572

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.

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

721 : 1, 7, 103, 721

953 : 1, 953

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,721,953,169, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

721:7x 103

953:953

169:13x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 78498537572/(1x169)

LCM = 78498537572/169

LCM = 464488388

Thus, we can understand that the LCM of 676,721,953,169 is 464488388.
