Given numbers are 947,690,551,963,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,690,551,963,405 is 1040155357770.
Find LCM of 947,690,551,963,405 with Prime Factorization
| 3 | 947, 690, 551, 963, 405 |
| 3 | 947, 230, 551, 321, 135 |
| 5 | 947, 230, 551, 107, 45 |
| 947, 46, 551, 107, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 947 x 46 x 551 x 107 x 9 = 1040155357770
Therefore, the lowest common multiple of 947,690,551,963,405 is 1040155357770.
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.
947 x 690 x 551 x 963 x 405 = 140420973298950
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.
947 : 1, 947
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
551 : 1, 19, 29, 551
963 : 1, 3, 9, 107, 321, 963
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,690,551,963,405, is 1.
Now, the common factors can be found like this.
947:947
690:2x 3x 5x 23
551:19x 29
963:3x 3x 107
405:3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 140420973298950/(1x135)
LCM = 140420973298950/135
LCM = 1040155357770
Thus, we can understand that the LCM of 947,690,551,963,405 is 1040155357770.
