Given numbers are 690,398,551,577

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

The LCM of 690,398,551,577 is 43654556370.

Find LCM of 690,398,551,577 with Prime Factorization

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

2 x 345 x 199 x 551 x 577 = 43654556370

Therefore, the lowest common multiple of 690,398,551,577 is 43654556370.

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 398 x 551 x 577 = 87309112740

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

398 : 1, 2, 199, 398

551 : 1, 19, 29, 551

577 : 1, 577

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,398,551,577, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

398:2x 199

551:19x 29

577:577

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 = 87309112740/(1x2)

LCM = 87309112740/2

LCM = 43654556370

Thus, we can understand that the LCM of 690,398,551,577 is 43654556370.
