Given numbers are 391,148,172,557

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

The LCM of 391,148,172,557 is 1385996468.

Find LCM of 391,148,172,557 with Prime Factorization

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

2 x 2 x 391 x 37 x 43 x 557 = 1385996468

Therefore, the lowest common multiple of 391,148,172,557 is 1385996468.

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.

391 x 148 x 172 x 557 = 5543985872

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.

391 : 1, 17, 23, 391

148 : 1, 2, 4, 37, 74, 148

172 : 1, 2, 4, 43, 86, 172

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,148,172,557, is 1.

Now, the common factors can be found like this.

391:17x 23

148:2x 2x 37

172:2x 2x 43

557:557

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 5543985872/(1x4)

LCM = 5543985872/4

LCM = 1385996468

Thus, we can understand that the LCM of 391,148,172,557 is 1385996468.
