Given numbers are 638,177,889,143

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

The LCM of 638,177,889,143 is 1305085782.

Find LCM of 638,177,889,143 with Prime Factorization

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

11 x 58 x 177 x 889 x 13 = 1305085782

Therefore, the lowest common multiple of 638,177,889,143 is 1305085782.

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 177 x 889 x 143 = 14355943602

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

177 : 1, 3, 59, 177

889 : 1, 7, 127, 889

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,177,889,143, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

177:3x 59

889:7x 127

143:11x 13

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 = 14355943602/(1x11)

LCM = 14355943602/11

LCM = 1305085782

Thus, we can understand that the LCM of 638,177,889,143 is 1305085782.
