Given numbers are 642,416,332,649,458

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

The LCM of 642,416,332,649,458 is 1647239070048.

Find LCM of 642,416,332,649,458 with Prime Factorization

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

2 x 2 x 321 x 104 x 83 x 649 x 229 = 1647239070048

Therefore, the lowest common multiple of 642,416,332,649,458 is 1647239070048.

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.

642 x 416 x 332 x 649 x 458 = 26355825120768

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

332 : 1, 2, 4, 83, 166, 332

649 : 1, 11, 59, 649

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,416,332,649,458, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

416:2x 2x 2x 2x 2x 13

332:2x 2x 83

649:11x 59

458:2x 229

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 2 = 16

Therefore, the value for common factors is 16.

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 = 26355825120768/(1x16)

LCM = 26355825120768/16

LCM = 1647239070048

Thus, we can understand that the LCM of 642,416,332,649,458 is 1647239070048.
