Given numbers are 223,407,678,642

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

The LCM of 223,407,678,642 is 6584347506.

Find LCM of 223,407,678,642 with Prime Factorization

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

2 x 3 x 223 x 407 x 113 x 107 = 6584347506

Therefore, the lowest common multiple of 223,407,678,642 is 6584347506.

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.

223 x 407 x 678 x 642 = 39506085036

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.

223 : 1, 223

407 : 1, 11, 37, 407

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,407,678,642, is 1.

Now, the common factors can be found like this.

223:223

407:11x 37

678:2x 3x 113

642:2x 3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 39506085036/(1x6)

LCM = 39506085036/6

LCM = 6584347506

Thus, we can understand that the LCM of 223,407,678,642 is 6584347506.
