Given numbers are 720,235,521,193

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

The LCM of 720,235,521,193 is 3402713520.

Find LCM of 720,235,521,193 with Prime Factorization

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

5 x 144 x 47 x 521 x 193 = 3402713520

Therefore, the lowest common multiple of 720,235,521,193 is 3402713520.

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 235 x 521 x 193 = 17013567600

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

235 : 1, 5, 47, 235

521 : 1, 521

193 : 1, 193

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,235,521,193, is 1.

Now, the common factors can be found like this.

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

235:5x 47

521:521

193:193

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

5 = 5

Therefore, the value for common factors is 5.

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 = 17013567600/(1x5)

LCM = 17013567600/5

LCM = 3402713520

Thus, we can understand that the LCM of 720,235,521,193 is 3402713520.
