Given numbers are 780,882,771,721

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

The LCM of 780,882,771,721 is 3035164860.

Find LCM of 780,882,771,721 with Prime Factorization

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

2 x 3 x 7 x 130 x 21 x 257 x 103 = 3035164860

Therefore, the lowest common multiple of 780,882,771,721 is 3035164860.

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 882 x 771 x 721 = 382430772360

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

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

771 : 1, 3, 257, 771

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,882,771,721, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

882:2x 3x 3x 7x 7

771:3x 257

721:7x 103

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

2x 3x 3x 7 = 126

Therefore, the value for common factors is 126.

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 = 382430772360/(1x126)

LCM = 382430772360/126

LCM = 3035164860

Thus, we can understand that the LCM of 780,882,771,721 is 3035164860.
