Given numbers are 640,326,163,976,716

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

The LCM of 640,326,163,976,716 is 1139070080.

Find LCM of 640,326,163,976,716 with Prime Factorization

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

2 x 2 x 2 x 2 x 163 x 40 x 1 x 1 x 61 x 179 = 1139070080

Therefore, the lowest common multiple of 640,326,163,976,716 is 1139070080.

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 326 x 163 x 976 x 716 = 23765558149120

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

326 : 1, 2, 163, 326

163 : 1, 163

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

716 : 1, 2, 4, 179, 358, 716

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,326,163,976,716, is 1.

Now, the common factors can be found like this.

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

326:2x 163

163:163

976:2x 2x 2x 2x 61

716:2x 2x 179

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 2x 2x 2x 2x 163 = 20864

Therefore, the value for common factors is 20864.

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 = 23765558149120/(1x20864)

LCM = 23765558149120/20864

LCM = 1139070080

Thus, we can understand that the LCM of 640,326,163,976,716 is 1139070080.
