Given numbers are 449,780,778,636

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

The LCM of 449,780,778,636 is 7220485740.

Find LCM of 449,780,778,636 with Prime Factorization

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

2 x 2 x 3 x 449 x 65 x 389 x 53 = 7220485740

Therefore, the lowest common multiple of 449,780,778,636 is 7220485740.

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.

449 x 780 x 778 x 636 = 173291657760

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.

449 : 1, 449

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

778 : 1, 2, 389, 778

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,780,778,636, is 1.

Now, the common factors can be found like this.

449:449

780:2x 2x 3x 5x 13

778:2x 389

636:2x 2x 3x 53

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 = 173291657760/(1x24)

LCM = 173291657760/24

LCM = 7220485740

Thus, we can understand that the LCM of 449,780,778,636 is 7220485740.
