Given numbers are 790,720,281,71

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

The LCM of 790,720,281,71 is 1134812880.

Find LCM of 790,720,281,71 with Prime Factorization

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

2 x 5 x 79 x 72 x 281 x 71 = 1134812880

Therefore, the lowest common multiple of 790,720,281,71 is 1134812880.

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.

790 x 720 x 281 x 71 = 11348128800

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.

790 : 1, 2, 5, 10, 79, 158, 395, 790

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

281 : 1, 281

71 : 1, 71

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,720,281,71, is 1.

Now, the common factors can be found like this.

790:2x 5x 79

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

281:281

71:71

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 11348128800/(1x10)

LCM = 11348128800/10

LCM = 1134812880

Thus, we can understand that the LCM of 790,720,281,71 is 1134812880.

Here are some samples of LCM of two or more Numbers calculations.
