The LCM of 786,960,497,955,154 is 131318214720.
Find LCM of 786,960,497,955,154 with Prime Factorization
| 2 | 786, 960, 497, 955, 154 |
| 3 | 393, 480, 497, 955, 77 |
| 5 | 131, 160, 497, 955, 77 |
| 7 | 131, 32, 497, 191, 77 |
| 131, 32, 71, 191, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 131 x 32 x 71 x 191 x 11 = 131318214720
Therefore, the lowest common multiple of 786,960,497,955,154 is 131318214720.
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.
786 x 960 x 497 x 955 x 154 = 55153650182400
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
497 : 1, 7, 71, 497
955 : 1, 5, 191, 955
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,960,497,955,154, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
960:2x 2x 2x 2x 2x 2x 3x 5
497:7x 71
955:5x 191
154:2x 7x 11
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 3x 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 55153650182400/(1x420)
LCM = 55153650182400/420
LCM = 131318214720
Thus, we can understand that the LCM of 786,960,497,955,154 is 131318214720.
