Given numbers are 520,988,610,420

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

The LCM of 520,988,610,420 is 12656280.

Find LCM of 520,988,610,420 with Prime Factorization

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

2 x 2 x 5 x 13 x 2 x 19 x 61 x 21 = 12656280

Therefore, the lowest common multiple of 520,988,610,420 is 12656280.

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.

520 x 988 x 610 x 420 = 131625312000

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

610 : 1, 2, 5, 10, 61, 122, 305, 610

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,988,610,420, is 2.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

988:2x 2x 13x 19

610:2x 5x 61

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.

2x 2x 2x 2x 5x 5x 13 = 5200

Therefore, the value for common factors is 5200.

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 = 131625312000/(2x5200)

LCM = 131625312000/10400

LCM = 12656280

Thus, we can understand that the LCM of 520,988,610,420 is 12656280.
