The LCM of 961,900,515,423,961 is 4186980900.
Find LCM of 961,900,515,423,961 with Prime Factorization
| 3 | 961, 900, 515, 423, 961 |
| 3 | 961, 300, 515, 141, 961 |
| 5 | 961, 100, 515, 47, 961 |
| 31 | 961, 20, 103, 47, 961 |
| 31 | 31, 20, 103, 47, 31 |
| 1, 20, 103, 47, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 31 x 31 x 1 x 20 x 103 x 47 x 1 = 4186980900
Therefore, the lowest common multiple of 961,900,515,423,961 is 4186980900.
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.
961 x 900 x 515 x 423 x 961 = 181065989020500
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.
961 : 1, 31, 961
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
515 : 1, 5, 103, 515
423 : 1, 3, 9, 47, 141, 423
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,900,515,423,961, is 1.
Now, the common factors can be found like this.
961:31x 31
900:2x 2x 3x 3x 5x 5
515:5x 103
423:3x 3x 47
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 31x 31 = 43245
Therefore, the value for common factors is 43245.
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 = 181065989020500/(1x43245)
LCM = 181065989020500/43245
LCM = 4186980900
Thus, we can understand that the LCM of 961,900,515,423,961 is 4186980900.
