Find LCM of 715,572,894,771 with Prime Factorization
| 2 | 715, 572, 894, 771 |
| 3 | 715, 286, 447, 771 |
| 11 | 715, 286, 149, 257 |
| 13 | 65, 26, 149, 257 |
| 5, 2, 149, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 5 x 2 x 149 x 257 = 328553940
Therefore, the lowest common multiple of 715,572,894,771 is 328553940.
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.
715 x 572 x 894 x 771 = 281899280520
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
894 : 1, 2, 3, 6, 149, 298, 447, 894
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,572,894,771, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
572:2x 2x 11x 13
894:2x 3x 149
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 13 = 858
Therefore, the value for common factors is 858.
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 = 281899280520/(1x858)
LCM = 281899280520/858
LCM = 328553940
Thus, we can understand that the LCM of 715,572,894,771 is 328553940.
