Given numbers are 605,748,660,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,748,660,695 is 17155380.
Find LCM of 605,748,660,695 with Prime Factorization
| 2 | 605, 748, 660, 695 |
| 2 | 605, 374, 330, 695 |
| 5 | 605, 187, 165, 695 |
| 11 | 121, 187, 33, 139 |
| 11, 17, 3, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 11 x 17 x 3 x 139 = 17155380
Therefore, the lowest common multiple of 605,748,660,695 is 17155380.
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.
605 x 748 x 660 x 695 = 207580098000
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.
605 : 1, 5, 11, 55, 121, 605
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,748,660,695, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
748:2x 2x 11x 17
660:2x 2x 3x 5x 11
695:5x 139
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 5x 5x 11x 11 = 12100
Therefore, the value for common factors is 12100.
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 = 207580098000/(1x12100)
LCM = 207580098000/12100
LCM = 17155380
Thus, we can understand that the LCM of 605,748,660,695 is 17155380.
