Given numbers are 646,334,425,781

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

The LCM of 646,334,425,781 is 2106396050.

Find LCM of 646,334,425,781 with Prime Factorization

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

2 x 17 x 19 x 167 x 25 x 781 = 2106396050

Therefore, the lowest common multiple of 646,334,425,781 is 2106396050.

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 334 x 425 x 781 = 71617465700

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

334 : 1, 2, 167, 334

425 : 1, 5, 17, 25, 85, 425

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,334,425,781, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

334:2x 167

425:5x 5x 17

781:11x 71

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 71617465700/(1x34)

LCM = 71617465700/34

LCM = 2106396050

Thus, we can understand that the LCM of 646,334,425,781 is 2106396050.
