Given numbers are 923,278,420

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

The LCM of 923,278,420 is 53884740.

Find LCM of 923,278,420 with Prime Factorization

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

2 x 923 x 139 x 210 = 53884740

Therefore, the lowest common multiple of 923,278,420 is 53884740.

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.

923 x 278 x 420 = 107769480

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.

923 : 1, 13, 71, 923

278 : 1, 2, 139, 278

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,278,420, is 1.

Now, the common factors can be found like this.

923:13x 71

278:2x 139

420:2x 2x 3x 5x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 107769480/(1x2)

LCM = 107769480/2

LCM = 53884740

Thus, we can understand that the LCM of 923,278,420 is 53884740.
