Given numbers are 905,739,817,689,720

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

The LCM of 905,739,817,689,720 is 54212169576240.

Find LCM of 905,739,817,689,720 with Prime Factorization

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

5 x 181 x 739 x 817 x 689 x 144 = 54212169576240

Therefore, the lowest common multiple of 905,739,817,689,720 is 54212169576240.

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.

905 x 739 x 817 x 689 x 720 = 271060847881200

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.

905 : 1, 5, 181, 905

739 : 1, 739

817 : 1, 19, 43, 817

689 : 1, 13, 53, 689

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,739,817,689,720, is 1.

Now, the common factors can be found like this.

905:5x 181

739:739

817:19x 43

689:13x 53

720:2x 2x 2x 2x 3x 3x 5

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

5 = 5

Therefore, the value for common factors is 5.

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 = 271060847881200/(1x5)

LCM = 271060847881200/5

LCM = 54212169576240

Thus, we can understand that the LCM of 905,739,817,689,720 is 54212169576240.
