The LCM of 451,805,434,947,943 is 21316411270.
Find LCM of 451,805,434,947,943 with Prime Factorization
| 7 | 451, 805, 434, 947, 943 |
| 23 | 451, 115, 62, 947, 943 |
| 41 | 451, 5, 62, 947, 41 |
| 11, 5, 62, 947, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 41 x 11 x 5 x 62 x 947 x 1 = 21316411270
Therefore, the lowest common multiple of 451,805,434,947,943 is 21316411270.
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.
451 x 805 x 434 x 947 x 943 = 140709630793270
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.
451 : 1, 11, 41, 451
805 : 1, 5, 7, 23, 35, 115, 161, 805
434 : 1, 2, 7, 14, 31, 62, 217, 434
947 : 1, 947
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,805,434,947,943, is 1.
Now, the common factors can be found like this.
451:11x 41
805:5x 7x 23
434:2x 7x 31
947:947
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23x 41 = 6601
Therefore, the value for common factors is 6601.
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 = 140709630793270/(1x6601)
LCM = 140709630793270/6601
LCM = 21316411270
Thus, we can understand that the LCM of 451,805,434,947,943 is 21316411270.
