The LCM of 722,855,437,415,943 is 2542959810.
Find LCM of 722,855,437,415,943 with Prime Factorization
| 5 | 722, 855, 437, 415, 943 |
| 19 | 722, 171, 437, 83, 943 |
| 23 | 38, 9, 23, 83, 943 |
| 38, 9, 1, 83, 41 |
Multiply the prime numbers at the bottom and the left side.
5 x 19 x 23 x 38 x 9 x 1 x 83 x 41 = 2542959810
Therefore, the lowest common multiple of 722,855,437,415,943 is 2542959810.
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.
722 x 855 x 437 x 415 x 943 = 105570976512150
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.
722 : 1, 2, 19, 38, 361, 722
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
437 : 1, 19, 23, 437
415 : 1, 5, 83, 415
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,855,437,415,943, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
855:3x 3x 5x 19
437:19x 23
415:5x 83
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.
5x 19x 19x 23 = 41515
Therefore, the value for common factors is 41515.
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 = 105570976512150/(1x41515)
LCM = 105570976512150/41515
LCM = 2542959810
Thus, we can understand that the LCM of 722,855,437,415,943 is 2542959810.
