Given numbers are 401,987,728,203

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

The LCM of 401,987,728,203 is 1193693592.

Find LCM of 401,987,728,203 with Prime Factorization

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

7 x 401 x 141 x 104 x 29 = 1193693592

Therefore, the lowest common multiple of 401,987,728,203 is 1193693592.

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.

401 x 987 x 728 x 203 = 58490986008

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.

401 : 1, 401

987 : 1, 3, 7, 21, 47, 141, 329, 987

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,987,728,203, is 1.

Now, the common factors can be found like this.

401:401

987:3x 7x 47

728:2x 2x 2x 7x 13

203:7x 29

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 58490986008/(1x49)

LCM = 58490986008/49

LCM = 1193693592

Thus, we can understand that the LCM of 401,987,728,203 is 1193693592.
