Given numbers are 691,915,770,368,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,915,770,368,762 is 2275314352080.
Find LCM of 691,915,770,368,762 with Prime Factorization
| 2 | 691, 915, 770, 368, 762 |
| 3 | 691, 915, 385, 184, 381 |
| 5 | 691, 305, 385, 184, 127 |
| 691, 61, 77, 184, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 691 x 61 x 77 x 184 x 127 = 2275314352080
Therefore, the lowest common multiple of 691,915,770,368,762 is 2275314352080.
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.
691 x 915 x 770 x 368 x 762 = 136518861124800
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.
691 : 1, 691
915 : 1, 3, 5, 15, 61, 183, 305, 915
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,915,770,368,762, is 1.
Now, the common factors can be found like this.
691:691
915:3x 5x 61
770:2x 5x 7x 11
368:2x 2x 2x 2x 23
762:2x 3x 127
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 5 = 60
Therefore, the value for common factors is 60.
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 = 136518861124800/(1x60)
LCM = 136518861124800/60
LCM = 2275314352080
Thus, we can understand that the LCM of 691,915,770,368,762 is 2275314352080.
