Given numbers are 446,121,780,365

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

The LCM of 446,121,780,365 is 1536412020.

Find LCM of 446,121,780,365 with Prime Factorization

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

2 x 5 x 223 x 121 x 78 x 73 = 1536412020

Therefore, the lowest common multiple of 446,121,780,365 is 1536412020.

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.

446 x 121 x 780 x 365 = 15364120200

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.

446 : 1, 2, 223, 446

121 : 1, 11, 121

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

365 : 1, 5, 73, 365

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,121,780,365, is 1.

Now, the common factors can be found like this.

446:2x 223

121:11x 11

780:2x 2x 3x 5x 13

365:5x 73

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 15364120200/(1x10)

LCM = 15364120200/10

LCM = 1536412020

Thus, we can understand that the LCM of 446,121,780,365 is 1536412020.
