Given numbers are 646,817,131,445

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

The LCM of 646,817,131,445 is 1619318510.

Find LCM of 646,817,131,445 with Prime Factorization

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

19 x 34 x 43 x 131 x 445 = 1619318510

Therefore, the lowest common multiple of 646,817,131,445 is 1619318510.

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 817 x 131 x 445 = 30767051690

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

817 : 1, 19, 43, 817

131 : 1, 131

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,817,131,445, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

817:19x 43

131:131

445:5x 89

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

19 = 19

Therefore, the value for common factors is 19.

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 = 30767051690/(1x19)

LCM = 30767051690/19

LCM = 1619318510

Thus, we can understand that the LCM of 646,817,131,445 is 1619318510.
