Given numbers are 653,391,655,917

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

The LCM of 653,391,655,917 is 1170655955.

Find LCM of 653,391,655,917 with Prime Factorization

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

131 x 653 x 391 x 5 x 7 = 1170655955

Therefore, the lowest common multiple of 653,391,655,917 is 1170655955.

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.

653 x 391 x 655 x 917 = 153355930105

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.

653 : 1, 653

391 : 1, 17, 23, 391

655 : 1, 5, 131, 655

917 : 1, 7, 131, 917

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,391,655,917, is 1.

Now, the common factors can be found like this.

653:653

391:17x 23

655:5x 131

917:7x 131

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

131 = 131

Therefore, the value for common factors is 131.

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 = 153355930105/(1x131)

LCM = 153355930105/131

LCM = 1170655955

Thus, we can understand that the LCM of 653,391,655,917 is 1170655955.
