Find LCM of 698,336,872,948,640 with Prime Factorization
| 2 | 698, 336, 872, 948, 640 |
| 2 | 349, 168, 436, 474, 320 |
| 2 | 349, 84, 218, 237, 160 |
| 2 | 349, 42, 109, 237, 80 |
| 3 | 349, 21, 109, 237, 40 |
| 349, 7, 109, 79, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 349 x 7 x 109 x 79 x 40 = 40390412160
Therefore, the lowest common multiple of 698,336,872,948,640 is 40390412160.
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.
698 x 336 x 872 x 948 x 640 = 124079346155520
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.
698 : 1, 2, 349, 698
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
872 : 1, 2, 4, 8, 109, 218, 436, 872
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,336,872,948,640, is 2.
Now, the common factors can be found like this.
698:2x 349
336:2x 2x 2x 2x 3x 7
872:2x 2x 2x 109
948:2x 2x 3x 79
640:2x 2x 2x 2x 2x 2x 2x 5
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 2x 2x 2x 2x 2x 2x 3 = 1536
Therefore, the value for common factors is 1536.
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 = 124079346155520/(2x1536)
LCM = 124079346155520/3072
LCM = 40390412160
Thus, we can understand that the LCM of 698,336,872,948,640 is 40390412160.
