Given numbers are 720,312,318,146

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

The LCM of 720,312,318,146 is 36213840.

Find LCM of 720,312,318,146 with Prime Factorization

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

2 x 2 x 2 x 3 x 30 x 13 x 53 x 73 = 36213840

Therefore, the lowest common multiple of 720,312,318,146 is 36213840.

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 312 x 318 x 146 = 10429585920

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

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

318 : 1, 2, 3, 6, 53, 106, 159, 318

146 : 1, 2, 73, 146

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,312,318,146, is 2.

Now, the common factors can be found like this.

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

312:2x 2x 2x 3x 13

318:2x 3x 53

146:2x 73

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

2x 2x 2x 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 10429585920/(2x144)

LCM = 10429585920/288

LCM = 36213840

Thus, we can understand that the LCM of 720,312,318,146 is 36213840.
