Given numbers are 988,124,732,990,392

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

The LCM of 988,124,732,990,392 is 90631621080.

Find LCM of 988,124,732,990,392 with Prime Factorization

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

2 x 2 x 3 x 247 x 31 x 61 x 165 x 98 = 90631621080

Therefore, the lowest common multiple of 988,124,732,990,392 is 90631621080.

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.

988 x 124 x 732 x 990 x 392 = 34802542494720

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.

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

124 : 1, 2, 4, 31, 62, 124

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,124,732,990,392, is 2.

Now, the common factors can be found like this.

988:2x 2x 13x 19

124:2x 2x 31

732:2x 2x 3x 61

990:2x 3x 3x 5x 11

392:2x 2x 2x 7x 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 2x 2x 3 = 192

Therefore, the value for common factors is 192.

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 = 34802542494720/(2x192)

LCM = 34802542494720/384

LCM = 90631621080

Thus, we can understand that the LCM of 988,124,732,990,392 is 90631621080.
