Given numbers are 407,678,113,391

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

The LCM of 407,678,113,391 is 107894886.

Find LCM of 407,678,113,391 with Prime Factorization

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

113 x 407 x 6 x 1 x 391 = 107894886

Therefore, the lowest common multiple of 407,678,113,391 is 107894886.

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.

407 x 678 x 113 x 391 = 12192122118

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.

407 : 1, 11, 37, 407

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

113 : 1, 113

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,678,113,391, is 1.

Now, the common factors can be found like this.

407:11x 37

678:2x 3x 113

113:113

391:17x 23

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

113 = 113

Therefore, the value for common factors is 113.

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 = 12192122118/(1x113)

LCM = 12192122118/113

LCM = 107894886

Thus, we can understand that the LCM of 407,678,113,391 is 107894886.
