Given numbers are 689,817,424,970

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

The LCM of 689,817,424,970 is 2184102440.

Find LCM of 689,817,424,970 with Prime Factorization

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

2 x 53 x 13 x 817 x 4 x 485 = 2184102440

Therefore, the lowest common multiple of 689,817,424,970 is 2184102440.

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.

689 x 817 x 424 x 970 = 231514858640

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.

689 : 1, 13, 53, 689

817 : 1, 19, 43, 817

424 : 1, 2, 4, 8, 53, 106, 212, 424

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,817,424,970, is 1.

Now, the common factors can be found like this.

689:13x 53

817:19x 43

424:2x 2x 2x 53

970:2x 5x 97

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

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 231514858640/(1x106)

LCM = 231514858640/106

LCM = 2184102440

Thus, we can understand that the LCM of 689,817,424,970 is 2184102440.
