Given numbers are 364,421,689,460
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 364,421,689,460 is 934022180.
Find LCM of 364,421,689,460 with Prime Factorization
| 2 | 364, 421, 689, 460 |
| 2 | 182, 421, 689, 230 |
| 13 | 91, 421, 689, 115 |
| 7, 421, 53, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 7 x 421 x 53 x 115 = 934022180
Therefore, the lowest common multiple of 364,421,689,460 is 934022180.
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.
364 x 421 x 689 x 460 = 48569153360
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.
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
421 : 1, 421
689 : 1, 13, 53, 689
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 364,421,689,460, is 1.
Now, the common factors can be found like this.
364:2x 2x 7x 13
421:421
689:13x 53
460:2x 2x 5x 23
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 13 = 52
Therefore, the value for common factors is 52.
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 = 48569153360/(1x52)
LCM = 48569153360/52
LCM = 934022180
Thus, we can understand that the LCM of 364,421,689,460 is 934022180.
