Given numbers are 969,190,209,691

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

The LCM of 969,190,209,691 is 73653690.

Find LCM of 969,190,209,691 with Prime Factorization

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

19 x 51 x 10 x 11 x 691 = 73653690

Therefore, the lowest common multiple of 969,190,209,691 is 73653690.

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.

969 x 190 x 209 x 691 = 26588982090

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.

969 : 1, 3, 17, 19, 51, 57, 323, 969

190 : 1, 2, 5, 10, 19, 38, 95, 190

209 : 1, 11, 19, 209

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,190,209,691, is 1.

Now, the common factors can be found like this.

969:3x 17x 19

190:2x 5x 19

209:11x 19

691:691

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

19x 19 = 361

Therefore, the value for common factors is 361.

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 = 26588982090/(1x361)

LCM = 26588982090/361

LCM = 73653690

Thus, we can understand that the LCM of 969,190,209,691 is 73653690.
