Given numbers are 923,611,409,390

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

The LCM of 923,611,409,390 is 532284870.

Find LCM of 923,611,409,390 with Prime Factorization

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

13 x 71 x 47 x 409 x 30 = 532284870

Therefore, the lowest common multiple of 923,611,409,390 is 532284870.

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 611 x 409 x 390 = 89956143030

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

611 : 1, 13, 47, 611

409 : 1, 409

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,611,409,390, is 1.

Now, the common factors can be found like this.

923:13x 71

611:13x 47

409:409

390:2x 3x 5x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 89956143030/(1x169)

LCM = 89956143030/169

LCM = 532284870

Thus, we can understand that the LCM of 923,611,409,390 is 532284870.
