Given numbers are 77,89,638

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

The LCM of 77,89,638 is 397474.

Find LCM of 77,89,638 with Prime Factorization

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

11 x 7 x 89 x 58 = 397474

Therefore, the lowest common multiple of 77,89,638 is 397474.

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.

77 x 89 x 638 = 4372214

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.

77 : 1, 7, 11, 77

89 : 1, 89

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 77,89,638, is 1.

Now, the common factors can be found like this.

77:7x 11

89:89

638:2x 11x 29

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

11 = 11

Therefore, the value for common factors is 11.

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 = 4372214/(1x11)

LCM = 4372214/11

LCM = 397474

Thus, we can understand that the LCM of 77,89,638 is 397474.
