Given numbers are 551,506,390,223,647

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

The LCM of 551,506,390,223,647 is 7844149654770.

Find LCM of 551,506,390,223,647 with Prime Factorization

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

2 x 551 x 253 x 195 x 223 x 647 = 7844149654770

Therefore, the lowest common multiple of 551,506,390,223,647 is 7844149654770.

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.

551 x 506 x 390 x 223 x 647 = 15688299309540

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.

551 : 1, 19, 29, 551

506 : 1, 2, 11, 22, 23, 46, 253, 506

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

223 : 1, 223

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,506,390,223,647, is 1.

Now, the common factors can be found like this.

551:19x 29

506:2x 11x 23

390:2x 3x 5x 13

223:223

647:647

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 = 15688299309540/(1x2)

LCM = 15688299309540/2

LCM = 7844149654770

Thus, we can understand that the LCM of 551,506,390,223,647 is 7844149654770.
