Given numbers are 7,493,988,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,493,988,551 is 3409588.
Find LCM of 7,493,988,551 with Prime Factorization
| 19 | 7, 493, 988, 551 |
| 29 | 7, 493, 52, 29 |
| 7, 17, 52, 1 |
Multiply the prime numbers at the bottom and the left side.
19 x 29 x 7 x 17 x 52 x 1 = 3409588
Therefore, the lowest common multiple of 7,493,988,551 is 3409588.
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.
7 x 493 x 988 x 551 = 1878682988
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.
7 : 1, 7
493 : 1, 17, 29, 493
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,493,988,551, is 1.
Now, the common factors can be found like this.
7:7
493:17x 29
988:2x 2x 13x 19
551:19x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 29 = 551
Therefore, the value for common factors is 551.
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 = 1878682988/(1x551)
LCM = 1878682988/551
LCM = 3409588
Thus, we can understand that the LCM of 7,493,988,551 is 3409588.
