The LCM of 770,665,115,209 is 336490.

Find LCM of 770,665,115,209 with Prime Factorization


5 770, 665, 115, 209
7 154, 133, 23, 209
11 22, 19, 23, 209
19 2, 19, 23, 19
2, 1, 23, 1

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

5 x 7 x 11 x 19 x 2 x 1 x 23 x 1 = 336490

Therefore, the lowest common multiple of 770,665,115,209 is 336490.

LCM Formula to Find Lowest Common Multiple of 770,665,115,209

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.

770 x 665 x 115 x 209 = 12307121750

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.

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

665 : 1, 5, 7, 19, 35, 95, 133, 665

115 : 1, 5, 23, 115

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,665,115,209, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

665:5x 7x 19

115:5x 23

209:11x 19

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

5x 5x 7x 11x 19 = 36575

Therefore, the value for common factors is 36575.

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 = 12307121750/(1x36575)

LCM = 12307121750/36575

LCM = 336490

Thus, we can understand that the LCM of 770,665,115,209 is 336490.
