Given numbers are 479,680,690,272,646

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

The LCM of 479,680,690,272,646 is 854037840.

Find LCM of 479,680,690,272,646 with Prime Factorization

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

2 x 2 x 2 x 5 x 17 x 479 x 1 x 69 x 2 x 19 = 854037840

Therefore, the lowest common multiple of 479,680,690,272,646 is 854037840.

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.

479 x 680 x 690 x 272 x 646 = 39490709721600

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.

479 : 1, 479

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,680,690,272,646, is 1.

Now, the common factors can be found like this.

479:479

680:2x 2x 2x 5x 17

690:2x 3x 5x 23

272:2x 2x 2x 2x 17

646:2x 17x 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 2x 2x 2x 2x 5x 17x 17 = 46240

Therefore, the value for common factors is 46240.

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 = 39490709721600/(1x46240)

LCM = 39490709721600/46240

LCM = 854037840

Thus, we can understand that the LCM of 479,680,690,272,646 is 854037840.
