Given numbers are 155,680,527,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,680,527,790 is 1665320.
Find LCM of 155,680,527,790 with Prime Factorization
| 2 | 155, 680, 527, 790 |
| 5 | 155, 340, 527, 395 |
| 17 | 31, 68, 527, 79 |
| 31 | 31, 4, 31, 79 |
| 1, 4, 1, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 31 x 1 x 4 x 1 x 79 = 1665320
Therefore, the lowest common multiple of 155,680,527,790 is 1665320.
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.
155 x 680 x 527 x 790 = 43881182000
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.
155 : 1, 5, 31, 155
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
527 : 1, 17, 31, 527
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,680,527,790, is 1.
Now, the common factors can be found like this.
155:5x 31
680:2x 2x 2x 5x 17
527:17x 31
790:2x 5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 17x 31 = 26350
Therefore, the value for common factors is 26350.
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 = 43881182000/(1x26350)
LCM = 43881182000/26350
LCM = 1665320
Thus, we can understand that the LCM of 155,680,527,790 is 1665320.
