Given numbers are 644,676,307,701

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

The LCM of 644,676,307,701 is 23422269052.

Find LCM of 644,676,307,701 with Prime Factorization

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

2 x 2 x 161 x 169 x 307 x 701 = 23422269052

Therefore, the lowest common multiple of 644,676,307,701 is 23422269052.

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.

644 x 676 x 307 x 701 = 93689076208

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

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

307 : 1, 307

701 : 1, 701

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,676,307,701, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

676:2x 2x 13x 13

307:307

701:701

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 = 93689076208/(1x4)

LCM = 93689076208/4

LCM = 23422269052

Thus, we can understand that the LCM of 644,676,307,701 is 23422269052.
