Given numbers are 26,79,28,689

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

The LCM of 26,79,28,689 is 1524068.

Find LCM of 26,79,28,689 with Prime Factorization

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

2 x 13 x 1 x 79 x 14 x 53 = 1524068

Therefore, the lowest common multiple of 26,79,28,689 is 1524068.

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.

26 x 79 x 28 x 689 = 39625768

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.

26 : 1, 2, 13, 26

79 : 1, 79

28 : 1, 2, 4, 7, 14, 28

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 26,79,28,689, is 1.

Now, the common factors can be found like this.

26:2x 13

79:79

28:2x 2x 7

689:13x 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 13 = 26

Therefore, the value for common factors is 26.

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 = 39625768/(1x26)

LCM = 39625768/26

LCM = 1524068

Thus, we can understand that the LCM of 26,79,28,689 is 1524068.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 24, 80, 41, 323
