Given numbers are 781,874,638,199

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

The LCM of 781,874,638,199 is 3939249974.

Find LCM of 781,874,638,199 with Prime Factorization

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

2 x 11 x 71 x 437 x 29 x 199 = 3939249974

Therefore, the lowest common multiple of 781,874,638,199 is 3939249974.

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.

781 x 874 x 638 x 199 = 86663499428

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.

781 : 1, 11, 71, 781

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

199 : 1, 199

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,874,638,199, is 1.

Now, the common factors can be found like this.

781:11x 71

874:2x 19x 23

638:2x 11x 29

199:199

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 86663499428/(1x22)

LCM = 86663499428/22

LCM = 3939249974

Thus, we can understand that the LCM of 781,874,638,199 is 3939249974.
