Given numbers are 910,420,494,505

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

The LCM of 910,420,494,505 is 10477740.

Find LCM of 910,420,494,505 with Prime Factorization

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

2 x 5 x 7 x 13 x 1 x 6 x 19 x 101 = 10477740

Therefore, the lowest common multiple of 910,420,494,505 is 10477740.

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.

910 x 420 x 494 x 505 = 95347434000

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.

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

494 : 1, 2, 13, 19, 26, 38, 247, 494

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,420,494,505, is 1.

Now, the common factors can be found like this.

910:2x 5x 7x 13

420:2x 2x 3x 5x 7

494:2x 13x 19

505:5x 101

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 5x 5x 7x 13 = 9100

Therefore, the value for common factors is 9100.

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 = 95347434000/(1x9100)

LCM = 95347434000/9100

LCM = 10477740

Thus, we can understand that the LCM of 910,420,494,505 is 10477740.
