Given numbers are 780,874,681,678

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

The LCM of 780,874,681,678 is 8743399860.

Find LCM of 780,874,681,678 with Prime Factorization

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

2 x 3 x 130 x 437 x 227 x 113 = 8743399860

Therefore, the lowest common multiple of 780,874,681,678 is 8743399860.

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 874 x 681 x 678 = 314762394960

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

874 : 1, 2, 19, 23, 38, 46, 437, 874

681 : 1, 3, 227, 681

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,874,681,678, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

874:2x 19x 23

681:3x 227

678:2x 3x 113

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 314762394960/(1x36)

LCM = 314762394960/36

LCM = 8743399860

Thus, we can understand that the LCM of 780,874,681,678 is 8743399860.
