Given numbers are 139,420,742,114,752
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,420,742,114,752 is 11052268080.
Find LCM of 139,420,742,114,752 with Prime Factorization
| 2 | 139, 420, 742, 114, 752 |
| 2 | 139, 210, 371, 57, 376 |
| 3 | 139, 105, 371, 57, 188 |
| 7 | 139, 35, 371, 19, 188 |
| 139, 5, 53, 19, 188 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 139 x 5 x 53 x 19 x 188 = 11052268080
Therefore, the lowest common multiple of 139,420,742,114,752 is 11052268080.
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.
139 x 420 x 742 x 114 x 752 = 3713562074880
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.
139 : 1, 139
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
742 : 1, 2, 7, 14, 53, 106, 371, 742
114 : 1, 2, 3, 6, 19, 38, 57, 114
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,420,742,114,752, is 1.
Now, the common factors can be found like this.
139:139
420:2x 2x 3x 5x 7
742:2x 7x 53
114:2x 3x 19
752:2x 2x 2x 2x 47
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 2x 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 3713562074880/(1x336)
LCM = 3713562074880/336
LCM = 11052268080
Thus, we can understand that the LCM of 139,420,742,114,752 is 11052268080.
