Given numbers are 49,80,26,423

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

The LCM of 49,80,26,423 is 21556080.

Find LCM of 49,80,26,423 with Prime Factorization

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

2 x 49 x 40 x 13 x 423 = 21556080

Therefore, the lowest common multiple of 49,80,26,423 is 21556080.

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.

49 x 80 x 26 x 423 = 43112160

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.

49 : 1, 7, 49

80 : 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

26 : 1, 2, 13, 26

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 49,80,26,423, is 1.

Now, the common factors can be found like this.

49:7x 7

80:2x 2x 2x 2x 5

26:2x 13

423:3x 3x 47

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 = 43112160/(1x2)

LCM = 43112160/2

LCM = 21556080

Thus, we can understand that the LCM of 49,80,26,423 is 21556080.
