Given numbers are 638,704,143,202

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

The LCM of 638,704,143,202 is 26806208.

Find LCM of 638,704,143,202 with Prime Factorization

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

2 x 11 x 29 x 32 x 13 x 101 = 26806208

Therefore, the lowest common multiple of 638,704,143,202 is 26806208.

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 704 x 143 x 202 = 12974204672

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

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

143 : 1, 11, 13, 143

202 : 1, 2, 101, 202

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,704,143,202, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

704:2x 2x 2x 2x 2x 2x 11

143:11x 13

202:2x 101

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

2x 2x 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 12974204672/(1x484)

LCM = 12974204672/484

LCM = 26806208

Thus, we can understand that the LCM of 638,704,143,202 is 26806208.
