Given numbers are 964,638,984,990

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

The LCM of 964,638,984,990 is 1134734040.

Find LCM of 964,638,984,990 with Prime Factorization

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

2 x 2 x 3 x 11 x 241 x 29 x 82 x 15 = 1134734040

Therefore, the lowest common multiple of 964,638,984,990 is 1134734040.

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.

964 x 638 x 984 x 990 = 599139573120

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.

964 : 1, 2, 4, 241, 482, 964

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

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 964,638,984,990, is 2.

Now, the common factors can be found like this.

964:2x 2x 241

638:2x 11x 29

984:2x 2x 2x 3x 41

990:2x 3x 3x 5x 11

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

2x 2x 2x 3x 11 = 264

Therefore, the value for common factors is 264.

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 = 599139573120/(2x264)

LCM = 599139573120/528

LCM = 1134734040

Thus, we can understand that the LCM of 964,638,984,990 is 1134734040.
