Given numbers are 638,949,385,337

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

The LCM of 638,949,385,337 is 7141424290.

Find LCM of 638,949,385,337 with Prime Factorization

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

11 x 58 x 949 x 35 x 337 = 7141424290

Therefore, the lowest common multiple of 638,949,385,337 is 7141424290.

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.

638 x 949 x 385 x 337 = 78555667190

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.

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

949 : 1, 13, 73, 949

385 : 1, 5, 7, 11, 35, 55, 77, 385

337 : 1, 337

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,949,385,337, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

949:13x 73

385:5x 7x 11

337:337

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

11 = 11

Therefore, the value for common factors is 11.

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 = 78555667190/(1x11)

LCM = 78555667190/11

LCM = 7141424290

Thus, we can understand that the LCM of 638,949,385,337 is 7141424290.
