Find LCM of 630,951,935,561 with Prime Factorization
| 3 | 630, 951, 935, 561 |
| 5 | 210, 317, 935, 187 |
| 11 | 42, 317, 187, 187 |
| 17 | 42, 317, 17, 17 |
| 42, 317, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 17 x 42 x 317 x 1 x 1 = 37345770
Therefore, the lowest common multiple of 630,951,935,561 is 37345770.
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.
630 x 951 x 935 x 561 = 314264654550
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.
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
951 : 1, 3, 317, 951
935 : 1, 5, 11, 17, 55, 85, 187, 935
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,951,935,561, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
951:3x 317
935:5x 11x 17
561:3x 11x 17
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 11x 17 = 8415
Therefore, the value for common factors is 8415.
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 = 314264654550/(1x8415)
LCM = 314264654550/8415
LCM = 37345770
Thus, we can understand that the LCM of 630,951,935,561 is 37345770.
