Find LCM of 692,552,905,391,715 with Prime Factorization
| 2 | 692, 552, 905, 391, 715 |
| 2 | 346, 276, 905, 391, 715 |
| 5 | 173, 138, 905, 391, 715 |
| 23 | 173, 138, 181, 391, 143 |
| 173, 6, 181, 17, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 173 x 6 x 181 x 17 x 143 = 210096452280
Therefore, the lowest common multiple of 692,552,905,391,715 is 210096452280.
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.
692 x 552 x 905 x 391 x 715 = 96644368048800
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.
692 : 1, 2, 4, 173, 346, 692
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
905 : 1, 5, 181, 905
391 : 1, 17, 23, 391
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,552,905,391,715, is 1.
Now, the common factors can be found like this.
692:2x 2x 173
552:2x 2x 2x 3x 23
905:5x 181
391:17x 23
715:5x 11x 13
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 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 96644368048800/(1x460)
LCM = 96644368048800/460
LCM = 210096452280
Thus, we can understand that the LCM of 692,552,905,391,715 is 210096452280.
