Given numbers are 390,126,710,805,635
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,126,710,805,635 is 1698532290.
Find LCM of 390,126,710,805,635 with Prime Factorization
| 2 | 390, 126, 710, 805, 635 |
| 3 | 195, 63, 355, 805, 635 |
| 5 | 65, 21, 355, 805, 635 |
| 7 | 13, 21, 71, 161, 127 |
| 13, 3, 71, 23, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 3 x 71 x 23 x 127 = 1698532290
Therefore, the lowest common multiple of 390,126,710,805,635 is 1698532290.
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.
390 x 126 x 710 x 805 x 635 = 17834589045000
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
710 : 1, 2, 5, 10, 71, 142, 355, 710
805 : 1, 5, 7, 23, 35, 115, 161, 805
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,126,710,805,635, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
126:2x 3x 3x 7
710:2x 5x 71
805:5x 7x 23
635:5x 127
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 5x 5x 5x 7 = 10500
Therefore, the value for common factors is 10500.
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 = 17834589045000/(1x10500)
LCM = 17834589045000/10500
LCM = 1698532290
Thus, we can understand that the LCM of 390,126,710,805,635 is 1698532290.
