Given numbers are 637,212,915,870,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,212,915,870,943 is 3379139165220.
Find LCM of 637,212,915,870,943 with Prime Factorization
| 2 | 637, 212, 915, 870, 943 |
| 3 | 637, 106, 915, 435, 943 |
| 5 | 637, 106, 305, 145, 943 |
| 637, 106, 61, 29, 943 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 637 x 106 x 61 x 29 x 943 = 3379139165220
Therefore, the lowest common multiple of 637,212,915,870,943 is 3379139165220.
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.
637 x 212 x 915 x 870 x 943 = 101374174956600
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.
637 : 1, 7, 13, 49, 91, 637
212 : 1, 2, 4, 53, 106, 212
915 : 1, 3, 5, 15, 61, 183, 305, 915
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,212,915,870,943, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
212:2x 2x 53
915:3x 5x 61
870:2x 3x 5x 29
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.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 101374174956600/(1x30)
LCM = 101374174956600/30
LCM = 3379139165220
Thus, we can understand that the LCM of 637,212,915,870,943 is 3379139165220.
