Given numbers are 780,311,678,699

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

The LCM of 780,311,678,699 is 6386888820.

Find LCM of 780,311,678,699 with Prime Factorization

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

2 x 3 x 130 x 311 x 113 x 233 = 6386888820

Therefore, the lowest common multiple of 780,311,678,699 is 6386888820.

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 311 x 678 x 699 = 114963998760

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

311 : 1, 311

678 : 1, 2, 3, 6, 113, 226, 339, 678

699 : 1, 3, 233, 699

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,311,678,699, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

311:311

678:2x 3x 113

699:3x 233

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 3 = 18

Therefore, the value for common factors is 18.

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 = 114963998760/(1x18)

LCM = 114963998760/18

LCM = 6386888820

Thus, we can understand that the LCM of 780,311,678,699 is 6386888820.
