Given numbers are 403,898,680,128,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,898,680,128,761 is 1498183256960.
Find LCM of 403,898,680,128,761 with Prime Factorization
| 2 | 403, 898, 680, 128, 761 |
| 2 | 403, 449, 340, 64, 761 |
| 2 | 403, 449, 170, 32, 761 |
| 403, 449, 85, 16, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 403 x 449 x 85 x 16 x 761 = 1498183256960
Therefore, the lowest common multiple of 403,898,680,128,761 is 1498183256960.
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.
403 x 898 x 680 x 128 x 761 = 23970932111360
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.
403 : 1, 13, 31, 403
898 : 1, 2, 449, 898
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
128 : 1, 2, 4, 8, 16, 32, 64, 128
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,898,680,128,761, is 1.
Now, the common factors can be found like this.
403:13x 31
898:2x 449
680:2x 2x 2x 5x 17
128:2x 2x 2x 2x 2x 2x 2
761:761
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 23970932111360/(1x16)
LCM = 23970932111360/16
LCM = 1498183256960
Thus, we can understand that the LCM of 403,898,680,128,761 is 1498183256960.
