Given numbers are 780,909,707,841

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

The LCM of 780,909,707,841 is 1391333580.

Find LCM of 780,909,707,841 with Prime Factorization

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

3 x 101 x 260 x 3 x 7 x 841 = 1391333580

Therefore, the lowest common multiple of 780,909,707,841 is 1391333580.

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.

780 x 909 x 707 x 841 = 421574074740

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

909 : 1, 3, 9, 101, 303, 909

707 : 1, 7, 101, 707

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,909,707,841, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

909:3x 3x 101

707:7x 101

841:29x 29

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

3x 101 = 303

Therefore, the value for common factors is 303.

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 = 421574074740/(1x303)

LCM = 421574074740/303

LCM = 1391333580

Thus, we can understand that the LCM of 780,909,707,841 is 1391333580.
