Given numbers are 678,740,691,230

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

The LCM of 678,740,691,230 is 3986917980.

Find LCM of 678,740,691,230 with Prime Factorization

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

2 x 5 x 339 x 74 x 691 x 23 = 3986917980

Therefore, the lowest common multiple of 678,740,691,230 is 3986917980.

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.

678 x 740 x 691 x 230 = 79738359600

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.

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

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

691 : 1, 691

230 : 1, 2, 5, 10, 23, 46, 115, 230

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,740,691,230, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

740:2x 2x 5x 37

691:691

230:2x 5x 23

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 5 = 20

Therefore, the value for common factors is 20.

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 = 79738359600/(1x20)

LCM = 79738359600/20

LCM = 3986917980

Thus, we can understand that the LCM of 678,740,691,230 is 3986917980.
