Given numbers are 154,632,395,921

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

The LCM of 154,632,395,921 is 224097720.

Find LCM of 154,632,395,921 with Prime Factorization

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

2 x 79 x 77 x 4 x 5 x 921 = 224097720

Therefore, the lowest common multiple of 154,632,395,921 is 224097720.

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.

154 x 632 x 395 x 921 = 35407439760

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.

154 : 1, 2, 7, 11, 14, 22, 77, 154

632 : 1, 2, 4, 8, 79, 158, 316, 632

395 : 1, 5, 79, 395

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,632,395,921, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

632:2x 2x 2x 79

395:5x 79

921:3x 307

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

2x 79 = 158

Therefore, the value for common factors is 158.

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 = 35407439760/(1x158)

LCM = 35407439760/158

LCM = 224097720

Thus, we can understand that the LCM of 154,632,395,921 is 224097720.
