Given numbers are 678,402,101,819

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

The LCM of 678,402,101,819 is 1252531098.

Find LCM of 678,402,101,819 with Prime Factorization

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

2 x 3 x 113 x 67 x 101 x 273 = 1252531098

Therefore, the lowest common multiple of 678,402,101,819 is 1252531098.

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 402 x 101 x 819 = 22545559764

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

402 : 1, 2, 3, 6, 67, 134, 201, 402

101 : 1, 101

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,402,101,819, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

402:2x 3x 67

101:101

819:3x 3x 7x 13

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 = 22545559764/(1x18)

LCM = 22545559764/18

LCM = 1252531098

Thus, we can understand that the LCM of 678,402,101,819 is 1252531098.
