Given numbers are 420,655,155,529

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

The LCM of 420,655,155,529 is 902272980.

Find LCM of 420,655,155,529 with Prime Factorization

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

5 x 84 x 131 x 31 x 529 = 902272980

Therefore, the lowest common multiple of 420,655,155,529 is 902272980.

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.

420 x 655 x 155 x 529 = 22556824500

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.

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

655 : 1, 5, 131, 655

155 : 1, 5, 31, 155

529 : 1, 23, 529

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,655,155,529, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

655:5x 131

155:5x 31

529:23x 23

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 22556824500/(1x25)

LCM = 22556824500/25

LCM = 902272980

Thus, we can understand that the LCM of 420,655,155,529 is 902272980.

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