Given numbers are 391,157,942,224

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

The LCM of 391,157,942,224 is 41252064.

Find LCM of 391,157,942,224 with Prime Factorization

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

2 x 157 x 391 x 1 x 3 x 112 = 41252064

Therefore, the lowest common multiple of 391,157,942,224 is 41252064.

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 157 x 942 x 224 = 12953148096

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

157 : 1, 157

942 : 1, 2, 3, 6, 157, 314, 471, 942

224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,157,942,224, is 1.

Now, the common factors can be found like this.

391:17x 23

157:157

942:2x 3x 157

224:2x 2x 2x 2x 2x 7

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

2x 157 = 314

Therefore, the value for common factors is 314.

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 = 12953148096/(1x314)

LCM = 12953148096/314

LCM = 41252064

Thus, we can understand that the LCM of 391,157,942,224 is 41252064.
