Find LCM of 784,529,858,624,692 with Prime Factorization
| 2 | 784, 529, 858, 624, 692 |
| 2 | 392, 529, 429, 312, 346 |
| 2 | 196, 529, 429, 156, 173 |
| 2 | 98, 529, 429, 78, 173 |
| 3 | 49, 529, 429, 39, 173 |
| 13 | 49, 529, 143, 13, 173 |
| 49, 529, 11, 1, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 49 x 529 x 11 x 1 x 173 = 30780461712
Therefore, the lowest common multiple of 784,529,858,624,692 is 30780461712.
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 529 x 858 x 624 x 692 = 153656064866304
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
529 : 1, 23, 529
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
692 : 1, 2, 4, 173, 346, 692
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,529,858,624,692, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
529:23x 23
858:2x 3x 11x 13
624:2x 2x 2x 2x 3x 13
692:2x 2x 173
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 3x 13 = 4992
Therefore, the value for common factors is 4992.
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 = 153656064866304/(1x4992)
LCM = 153656064866304/4992
LCM = 30780461712
Thus, we can understand that the LCM of 784,529,858,624,692 is 30780461712.
