Given numbers are 655,147,720,591,661

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

The LCM of 655,147,720,591,661 is 601821304560.

Find LCM of 655,147,720,591,661 with Prime Factorization

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

3 x 5 x 131 x 49 x 48 x 197 x 661 = 601821304560

Therefore, the lowest common multiple of 655,147,720,591,661 is 601821304560.

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.

655 x 147 x 720 x 591 x 661 = 27081958705200

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.

655 : 1, 5, 131, 655

147 : 1, 3, 7, 21, 49, 147

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

591 : 1, 3, 197, 591

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,147,720,591,661, is 1.

Now, the common factors can be found like this.

655:5x 131

147:3x 7x 7

720:2x 2x 2x 2x 3x 3x 5

591:3x 197

661:661

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

3x 3x 5 = 45

Therefore, the value for common factors is 45.

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 = 27081958705200/(1x45)

LCM = 27081958705200/45

LCM = 601821304560

Thus, we can understand that the LCM of 655,147,720,591,661 is 601821304560.
