Given numbers are 640,772,988

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

The LCM of 640,772,988 is 30509440.

Find LCM of 640,772,988 with Prime Factorization

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

2 x 2 x 160 x 193 x 247 = 30509440

Therefore, the lowest common multiple of 640,772,988 is 30509440.

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.

640 x 772 x 988 = 488151040

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

772 : 1, 2, 4, 193, 386, 772

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,772,988, is 4.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

772:2x 2x 193

988:2x 2x 13x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 488151040/(4x4)

LCM = 488151040/16

LCM = 30509440

Thus, we can understand that the LCM of 640,772,988 is 30509440.

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