Find LCM of 706,336,387,930,784 with Prime Factorization
| 2 | 706, 336, 387, 930, 784 |
| 2 | 353, 168, 387, 465, 392 |
| 2 | 353, 84, 387, 465, 196 |
| 2 | 353, 42, 387, 465, 98 |
| 3 | 353, 21, 387, 465, 49 |
| 7 | 353, 7, 129, 155, 49 |
| 353, 1, 129, 155, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 353 x 1 x 129 x 155 x 7 = 16600968720
Therefore, the lowest common multiple of 706,336,387,930,784 is 16600968720.
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.
706 x 336 x 387 x 930 x 784 = 66935105879040
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.
706 : 1, 2, 353, 706
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
387 : 1, 3, 9, 43, 129, 387
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,336,387,930,784, is 1.
Now, the common factors can be found like this.
706:2x 353
336:2x 2x 2x 2x 3x 7
387:3x 3x 43
930:2x 3x 5x 31
784:2x 2x 2x 2x 7x 7
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 3x 3x 7 = 4032
Therefore, the value for common factors is 4032.
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 = 66935105879040/(1x4032)
LCM = 66935105879040/4032
LCM = 16600968720
Thus, we can understand that the LCM of 706,336,387,930,784 is 16600968720.
