Given numbers are 609,165,690,549,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,165,690,549,578 is 81486702990.
Find LCM of 609,165,690,549,578 with Prime Factorization
| 2 | 609, 165, 690, 549, 578 |
| 3 | 609, 165, 345, 549, 289 |
| 5 | 203, 55, 115, 183, 289 |
| 203, 11, 23, 183, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 203 x 11 x 23 x 183 x 289 = 81486702990
Therefore, the lowest common multiple of 609,165,690,549,578 is 81486702990.
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.
609 x 165 x 690 x 549 x 578 = 22001409807300
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
165 : 1, 3, 5, 11, 15, 33, 55, 165
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
549 : 1, 3, 9, 61, 183, 549
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,165,690,549,578, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
165:3x 5x 11
690:2x 3x 5x 23
549:3x 3x 61
578:2x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 22001409807300/(1x270)
LCM = 22001409807300/270
LCM = 81486702990
Thus, we can understand that the LCM of 609,165,690,549,578 is 81486702990.
