Given numbers are 578,340,761,740,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,340,761,740,680 is 325494920.
Find LCM of 578,340,761,740,680 with Prime Factorization
| 2 | 578, 340, 761, 740, 680 |
| 2 | 289, 170, 761, 370, 340 |
| 5 | 289, 85, 761, 185, 170 |
| 17 | 289, 17, 761, 37, 34 |
| 1, 17, 761, 37, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 1 x 17 x 761 x 37 x 2 = 325494920
Therefore, the lowest common multiple of 578,340,761,740,680 is 325494920.
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.
578 x 340 x 761 x 740 x 680 = 75254425504000
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.
578 : 1, 2, 17, 34, 289, 578
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
761 : 1, 761
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,340,761,740,680, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
340:2x 2x 5x 17
761:761
740:2x 2x 5x 37
680:2x 2x 2x 5x 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 2x 2x 2x 2x 5x 5x 17x 17 = 231200
Therefore, the value for common factors is 231200.
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 = 75254425504000/(1x231200)
LCM = 75254425504000/231200
LCM = 325494920
Thus, we can understand that the LCM of 578,340,761,740,680 is 325494920.
