Given numbers are 320,417,445,646,763

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

The LCM of 320,417,445,646,763 is 2926867755840.

Find LCM of 320,417,445,646,763 with Prime Factorization

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

2 x 5 x 32 x 417 x 89 x 323 x 763 = 2926867755840

Therefore, the lowest common multiple of 320,417,445,646,763 is 2926867755840.

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.

320 x 417 x 445 x 646 x 763 = 29268677558400

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.

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

417 : 1, 3, 139, 417

445 : 1, 5, 89, 445

646 : 1, 2, 17, 19, 34, 38, 323, 646

763 : 1, 7, 109, 763

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,417,445,646,763, is 1.

Now, the common factors can be found like this.

320:2x 2x 2x 2x 2x 2x 5

417:3x 139

445:5x 89

646:2x 17x 19

763:7x 109

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 29268677558400/(1x10)

LCM = 29268677558400/10

LCM = 2926867755840

Thus, we can understand that the LCM of 320,417,445,646,763 is 2926867755840.
