Given numbers are 720,535,565,175,661

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

The LCM of 720,535,565,175,661 is 201402205200.

Find LCM of 720,535,565,175,661 with Prime Factorization

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

5 x 144 x 107 x 113 x 35 x 661 = 201402205200

Therefore, the lowest common multiple of 720,535,565,175,661 is 201402205200.

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.

720 x 535 x 565 x 175 x 661 = 25175275650000

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.

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

535 : 1, 5, 107, 535

565 : 1, 5, 113, 565

175 : 1, 5, 7, 25, 35, 175

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,535,565,175,661, is 1.

Now, the common factors can be found like this.

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

535:5x 107

565:5x 113

175:5x 5x 7

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.

5x 5x 5 = 125

Therefore, the value for common factors is 125.

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 = 25175275650000/(1x125)

LCM = 25175275650000/125

LCM = 201402205200

Thus, we can understand that the LCM of 720,535,565,175,661 is 201402205200.
