Given numbers are 641,274,465,468,148
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 641,274,465,468,148 is 235699071660.
Find LCM of 641,274,465,468,148 with Prime Factorization
| 2 | 641, 274, 465, 468, 148 |
| 2 | 641, 137, 465, 234, 74 |
| 3 | 641, 137, 465, 117, 37 |
| 641, 137, 155, 39, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 641 x 137 x 155 x 39 x 37 = 235699071660
Therefore, the lowest common multiple of 641,274,465,468,148 is 235699071660.
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.
641 x 274 x 465 x 468 x 148 = 5656777719840
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.
641 : 1, 641
274 : 1, 2, 137, 274
465 : 1, 3, 5, 15, 31, 93, 155, 465
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
148 : 1, 2, 4, 37, 74, 148
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,274,465,468,148, is 1.
Now, the common factors can be found like this.
641:641
274:2x 137
465:3x 5x 31
468:2x 2x 3x 3x 13
148:2x 2x 37
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 3 = 24
Therefore, the value for common factors is 24.
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 = 5656777719840/(1x24)
LCM = 5656777719840/24
LCM = 235699071660
Thus, we can understand that the LCM of 641,274,465,468,148 is 235699071660.
