Given numbers are 374,420,448,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 374,420,448,961 is 1207631040.
Find LCM of 374,420,448,961 with Prime Factorization
| 2 | 374, 420, 448, 961 |
| 2 | 187, 210, 224, 961 |
| 7 | 187, 105, 112, 961 |
| 187, 15, 16, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 187 x 15 x 16 x 961 = 1207631040
Therefore, the lowest common multiple of 374,420,448,961 is 1207631040.
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.
374 x 420 x 448 x 961 = 67627338240
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.
374 : 1, 2, 11, 17, 22, 34, 187, 374
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
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 374,420,448,961, is 1.
Now, the common factors can be found like this.
374:2x 11x 17
420:2x 2x 3x 5x 7
448:2x 2x 2x 2x 2x 2x 7
961:31x 31
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 7 = 56
Therefore, the value for common factors is 56.
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 = 67627338240/(1x56)
LCM = 67627338240/56
LCM = 1207631040
Thus, we can understand that the LCM of 374,420,448,961 is 1207631040.
