Given numbers are 690,134,591,691

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

The LCM of 690,134,591,691 is 6293151210.

Find LCM of 690,134,591,691 with Prime Factorization

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

2 x 3 x 115 x 67 x 197 x 691 = 6293151210

Therefore, the lowest common multiple of 690,134,591,691 is 6293151210.

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.

690 x 134 x 591 x 691 = 37758907260

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

134 : 1, 2, 67, 134

591 : 1, 3, 197, 591

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,134,591,691, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

134:2x 67

591:3x 197

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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 37758907260/(1x6)

LCM = 37758907260/6

LCM = 6293151210

Thus, we can understand that the LCM of 690,134,591,691 is 6293151210.
