Given numbers are 670,578,620,289,944
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,578,620,289,944 is 2833194160.
Find LCM of 670,578,620,289,944 with Prime Factorization
| 2 | 670, 578, 620, 289, 944 |
| 2 | 335, 289, 310, 289, 472 |
| 5 | 335, 289, 155, 289, 236 |
| 17 | 67, 289, 31, 289, 236 |
| 17 | 67, 17, 31, 17, 236 |
| 67, 1, 31, 1, 236 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 17 x 67 x 1 x 31 x 1 x 236 = 2833194160
Therefore, the lowest common multiple of 670,578,620,289,944 is 2833194160.
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.
670 x 578 x 620 x 289 x 944 = 65503448979200
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
578 : 1, 2, 17, 34, 289, 578
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
289 : 1, 17, 289
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,578,620,289,944, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
578:2x 17x 17
620:2x 2x 5x 31
289:17x 17
944:2x 2x 2x 2x 59
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 5x 17x 17 = 23120
Therefore, the value for common factors is 23120.
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 = 65503448979200/(1x23120)
LCM = 65503448979200/23120
LCM = 2833194160
Thus, we can understand that the LCM of 670,578,620,289,944 is 2833194160.
