Find LCM of 741,728,551,715,438 with Prime Factorization
| 2 | 741, 728, 551, 715, 438 |
| 3 | 741, 364, 551, 715, 219 |
| 13 | 247, 364, 551, 715, 73 |
| 19 | 19, 28, 551, 55, 73 |
| 1, 28, 29, 55, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 1 x 28 x 29 x 55 x 73 = 4831586760
Therefore, the lowest common multiple of 741,728,551,715,438 is 4831586760.
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.
741 x 728 x 551 x 715 x 438 = 93085350518160
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
551 : 1, 19, 29, 551
715 : 1, 5, 11, 13, 55, 65, 143, 715
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,728,551,715,438, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
728:2x 2x 2x 7x 13
551:19x 29
715:5x 11x 13
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 13x 19 = 19266
Therefore, the value for common factors is 19266.
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 = 93085350518160/(1x19266)
LCM = 93085350518160/19266
LCM = 4831586760
Thus, we can understand that the LCM of 741,728,551,715,438 is 4831586760.
