Given numbers are 551,690,836,967,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,690,836,967,639 is 1722778518780.
Find LCM of 551,690,836,967,639 with Prime Factorization
| 2 | 551, 690, 836, 967, 639 |
| 3 | 551, 345, 418, 967, 639 |
| 19 | 551, 115, 418, 967, 213 |
| 29, 115, 22, 967, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 29 x 115 x 22 x 967 x 213 = 1722778518780
Therefore, the lowest common multiple of 551,690,836,967,639 is 1722778518780.
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.
551 x 690 x 836 x 967 x 639 = 196396751140920
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.
551 : 1, 19, 29, 551
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
967 : 1, 967
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,690,836,967,639, is 1.
Now, the common factors can be found like this.
551:19x 29
690:2x 3x 5x 23
836:2x 2x 11x 19
967:967
639:3x 3x 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 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 196396751140920/(1x114)
LCM = 196396751140920/114
LCM = 1722778518780
Thus, we can understand that the LCM of 551,690,836,967,639 is 1722778518780.
