Find LCM of 518,630,405,661,770 with Prime Factorization
| 2 | 518, 630, 405, 661, 770 |
| 3 | 259, 315, 405, 661, 385 |
| 3 | 259, 105, 135, 661, 385 |
| 5 | 259, 35, 45, 661, 385 |
| 7 | 259, 7, 9, 661, 77 |
| 37, 1, 9, 661, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 37 x 1 x 9 x 661 x 11 = 1525383090
Therefore, the lowest common multiple of 518,630,405,661,770 is 1525383090.
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.
518 x 630 x 405 x 661 x 770 = 67269394269000
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
661 : 1, 661
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,630,405,661,770, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
630:2x 3x 3x 5x 7
405:3x 3x 3x 3x 5
661:661
770:2x 5x 7x 11
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 3x 3x 5x 5x 7x 7 = 44100
Therefore, the value for common factors is 44100.
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 = 67269394269000/(1x44100)
LCM = 67269394269000/44100
LCM = 1525383090
Thus, we can understand that the LCM of 518,630,405,661,770 is 1525383090.
