Given numbers are 689,137,677,430,770

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

The LCM of 689,137,677,430,770 is 2115863459710.

Find LCM of 689,137,677,430,770 with Prime Factorization

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

2 x 5 x 689 x 137 x 677 x 43 x 77 = 2115863459710

Therefore, the lowest common multiple of 689,137,677,430,770 is 2115863459710.

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 137 x 677 x 430 x 770 = 21158634597100

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

137 : 1, 137

677 : 1, 677

430 : 1, 2, 5, 10, 43, 86, 215, 430

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,137,677,430,770, is 1.

Now, the common factors can be found like this.

689:13x 53

137:137

677:677

430:2x 5x 43

770:2x 5x 7x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 21158634597100/(1x10)

LCM = 21158634597100/10

LCM = 2115863459710

Thus, we can understand that the LCM of 689,137,677,430,770 is 2115863459710.
