Given numbers are 690,551,764

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

The LCM of 690,551,764 is 145232580.

Find LCM of 690,551,764 with Prime Factorization

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

2 x 345 x 551 x 382 = 145232580

Therefore, the lowest common multiple of 690,551,764 is 145232580.

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 551 x 764 = 290465160

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

551 : 1, 19, 29, 551

764 : 1, 2, 4, 191, 382, 764

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,551,764, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

551:19x 29

764:2x 2x 191

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

2 = 2

Therefore, the value for common factors is 2.

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 = 290465160/(1x2)

LCM = 290465160/2

LCM = 145232580

Thus, we can understand that the LCM of 690,551,764 is 145232580.
