Given numbers are 638,255,706,803

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

The LCM of 638,255,706,803 is 4192358610.

Find LCM of 638,255,706,803 with Prime Factorization

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

2 x 11 x 29 x 255 x 353 x 73 = 4192358610

Therefore, the lowest common multiple of 638,255,706,803 is 4192358610.

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 255 x 706 x 803 = 92231889420

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

255 : 1, 3, 5, 15, 17, 51, 85, 255

706 : 1, 2, 353, 706

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,255,706,803, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

255:3x 5x 17

706:2x 353

803:11x 73

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 = 92231889420/(1x22)

LCM = 92231889420/22

LCM = 4192358610

Thus, we can understand that the LCM of 638,255,706,803 is 4192358610.
