Given numbers are 154,461,804,780

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

The LCM of 154,461,804,780 is 1855073220.

Find LCM of 154,461,804,780 with Prime Factorization

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

2 x 2 x 3 x 77 x 461 x 67 x 65 = 1855073220

Therefore, the lowest common multiple of 154,461,804,780 is 1855073220.

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 461 x 804 x 780 = 44521757280

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

461 : 1, 461

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,461,804,780, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

461:461

804:2x 2x 3x 67

780:2x 2x 3x 5x 13

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

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 44521757280/(1x24)

LCM = 44521757280/24

LCM = 1855073220

Thus, we can understand that the LCM of 154,461,804,780 is 1855073220.
