Given numbers are 76,26,643

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

The LCM of 76,26,643 is 635284.

Find LCM of 76,26,643 with Prime Factorization

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

2 x 38 x 13 x 643 = 635284

Therefore, the lowest common multiple of 76,26,643 is 635284.

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.

76 x 26 x 643 = 1270568

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.

76 : 1, 2, 4, 19, 38, 76

26 : 1, 2, 13, 26

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 76,26,643, is 1.

Now, the common factors can be found like this.

76:2x 2x 19

26:2x 13

643:643

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

2 = 2

Therefore, the value for common factors is 2.

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 = 1270568/(1x2)

LCM = 1270568/2

LCM = 635284

Thus, we can understand that the LCM of 76,26,643 is 635284.
