Given numbers are 646,785,314,689

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

The LCM of 646,785,314,689 is 349398790.

Find LCM of 646,785,314,689 with Prime Factorization

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

2 x 157 x 323 x 5 x 1 x 689 = 349398790

Therefore, the lowest common multiple of 646,785,314,689 is 349398790.

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.

646 x 785 x 314 x 689 = 109711220060

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.

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

785 : 1, 5, 157, 785

314 : 1, 2, 157, 314

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,785,314,689, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

785:5x 157

314:2x 157

689:13x 53

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

2x 157 = 314

Therefore, the value for common factors is 314.

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 = 109711220060/(1x314)

LCM = 109711220060/314

LCM = 349398790

Thus, we can understand that the LCM of 646,785,314,689 is 349398790.
