Given numbers are 646,697,799,225

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

The LCM of 646,697,799,225 is 280089450.

Find LCM of 646,697,799,225 with Prime Factorization

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

17 x 38 x 41 x 47 x 225 = 280089450

Therefore, the lowest common multiple of 646,697,799,225 is 280089450.

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.

646 x 697 x 799 x 225 = 80945851050

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

697 : 1, 17, 41, 697

799 : 1, 17, 47, 799

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,697,799,225, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

697:17x 41

799:17x 47

225:3x 3x 5x 5

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

17x 17 = 289

Therefore, the value for common factors is 289.

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 = 80945851050/(1x289)

LCM = 80945851050/289

LCM = 280089450

Thus, we can understand that the LCM of 646,697,799,225 is 280089450.
