Given numbers are 648,746,691

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

The LCM of 648,746,691 is 167017464.

Find LCM of 648,746,691 with Prime Factorization

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

2 x 324 x 373 x 691 = 167017464

Therefore, the lowest common multiple of 648,746,691 is 167017464.

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.

648 x 746 x 691 = 334034928

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

746 : 1, 2, 373, 746

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,746,691, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

746:2x 373

691:691

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 = 334034928/(1x2)

LCM = 334034928/2

LCM = 167017464

Thus, we can understand that the LCM of 648,746,691 is 167017464.
