Find LCM of 784,721,248,515,967 with Prime Factorization
| 2 | 784, 721, 248, 515, 967 |
| 2 | 392, 721, 124, 515, 967 |
| 2 | 196, 721, 62, 515, 967 |
| 7 | 98, 721, 31, 515, 967 |
| 103 | 14, 103, 31, 515, 967 |
| 14, 1, 31, 5, 967 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 103 x 14 x 1 x 31 x 5 x 967 = 12103513520
Therefore, the lowest common multiple of 784,721,248,515,967 is 12103513520.
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.
784 x 721 x 248 x 515 x 967 = 69813065983360
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
721 : 1, 7, 103, 721
248 : 1, 2, 4, 8, 31, 62, 124, 248
515 : 1, 5, 103, 515
967 : 1, 967
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,721,248,515,967, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
721:7x 103
248:2x 2x 2x 31
515:5x 103
967:967
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 7x 103 = 5768
Therefore, the value for common factors is 5768.
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 = 69813065983360/(1x5768)
LCM = 69813065983360/5768
LCM = 12103513520
Thus, we can understand that the LCM of 784,721,248,515,967 is 12103513520.
